Update Monday, 26th of March: Almost the next day or the following day I published this post KyngChaos just published the QGIS 3 release for macOS. You can download here.

Just a couple days ago I was about to write a post about how difficult, or almost impossible, is to install the last versions of QGIS on macOS right now. Everything started, I believe, when gdal package got update at the beginning of the week and that broke my install of QGIS 2 even thought, and to be honest, I really don’t know if all this mess was caused for that update, or by the update of the python formulae in Homebrew. Anyhow, usually these problems are solved just rebuilding the app from source using the new packages, but in this occasion that solution wasn’t working.

Homebrew decided that on the first of March the behavior of the Python formulae and the name, and I believe the name of the formulae, was going to change to be more consistent. To sum a little bit up, after the change python was going to point to python3 in your shell and python2 is going point to so python2 —or something like that. However, the change in the command in the CLI broke a truckload of third party software, and seems that also wasn’t compliant with Python’s policy. So… they decided to change some things back —CLI commands, no formulae names— and now seems that pythonpython2 and python3python3. If you are confused, don’t worry, am I also. Besides, since I’m not an expert in the matter and I’ve perhaps missed something in all this chaos. In consequence… I really don’t know!.

Anyhow and right now, with the current state of Homebrew and the OSGeo/homebrew-osgeo4mac tap, it’s quite difficult to install the last versions of QGIS in macOS. A few weeks ago, QGIS released QGIS 3 Girona, however it’s only possible to install it right now in Windows and Linux. Usually on macOS the releases has been a little bit slower than in other platforms basically because QGIS has really few developers able to work on macOS and seems that things aren’t as easy as in other platforms. Traditionally, Homebrew has come to the rescue with OSGeo/homebrew-osgeo4mac tap, which you can build your own version of QGIS, but that repo hasn’t been update almost since the beginning of December. This time the delay not only mean that the macOS users not only can’t install the last small incremental change version, but that for more than 3 weeks we aren’t able to install the last version, which means a big leap from version 2 to 3.

This left the macOS users a little bit hanging although we still can download the official build for macOS in the KyngChaos{.reference.external} download page, where you can find the 2.18.14 version. The problem is that version isn’t even the last version of the long-term repository release, which is 2.18.17.

Nevertheless, this weekend I was able to rebuild the last version of the LTR of QGIS 2 and the developer version of QGIS3. I really don’t know how stable is the QGIS 3 developer version, but at least at first sight everything works and the app even open faster than the QGIS 2.

## How to install the last version of QGIS 2?

What I did was just reinstall python, python2, gdal, gdal2, and finally qgis2. More or less as follows:


1
2
3
4
5

$brew reinstall python2 python bison && brew reinstall gdal2 \ --with-armadillo --with-complete --with-libkml \ --with-opencl --with-postgresql --with-unsupported$ brew reinstall qgis2 --with-grass --with-saga-gis-lts



After that and compiling here and there, I was able to open QGIS.app again.

This left me with QGIS in /usr/local/Cellar/qgis2/2.18.14. But I want to have QGIS.app in /Applications folder so I have two options. First one is run in the following command in the terminal, as advised by Homebrew:


1

$brew linkapps [--local]  However, I prefer to move the actual app to the /Applications folder and create a symbolic link on the /Cellar folder.  1 2$ mv -f /usr/local/Cellar/qgis2/2.18.14/QGIS.app /Applications
$ln -s /Applications/QGIS.app /usr/local/Cellar/qgis2/2.18.14/QGIS.app  Yet, weren’t we going to install the last version of QGIS? This isn’t the last version. OK… ### QGIS 2.18.17 To install the last version you need to change the the QGIS formulae to make it to download the last version from the LTR. Since Homebrew isn’t anything more than a git with Ruby scripts I recommend you to make a branch in the repository and change the formula. You aren’t going to change anything in Homebrew, but in a branch of tap, in the OSGeo/homebrew-osgeo4mac tap. I did the following. First, I create a branch and checked out on it.  1 2 3$ cd /usr/local/Homebrew/Library/Taps/osgeo/homebrew-osgeo4mac
$git checkout -b QGIS2.18.17$ brew edit qgis2



Now you can edit the formula to be able to install QGIS 2.18.17. ~You can see how I modify mine~~1 below that has highlighted the lines I’ve changed.

<pre class="nums:true lang:ruby mark:12-13 decode:true" title="qgis2.rb" data-url="https://raw.githubusercontent.com/luisspuerto/homebrew-osgeo4mac/QGIS2.18.17/Formula/qgis2.rb">



Now you just commit.


1
2

$git stage Formula/qgis2.rb$ git commit -m "qgis update to 2.18.17"



And now you just reinstall QGIS and move to /Applications:

$brew reinstall qgis2 --with-grass --with-saga-gis-lts$ mv -f /usr/local/Cellar/qgis2/2.18.17/QGIS.app /Applications
$ln -s /Applications/QGIS.app /usr/local/Cellar/qgis2/2.18.17/QGIS.app  ### Matplotlib Since Homebrew/homebrew-science has been deprecated and some of the formulae wasn’t migrated to the Homebrew/homebrew-core this left us with a message at the end of the QGIS’ compilation asking us to install matplotlib via pip. The following Python modules are needed by QGIS during run-time:  1 2 3 4 5 6 7 The following Python modules are needed by QGIS during run-time: matplotlib, pyparsing You can install manually, via installer package or with pip (if availble): pip install <module> OR pip-2.7 install <module>  I had a problem and when I tried to install using pip install matplotlib threw me an error, though.  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 Collecting matplotlib Using cached matplotlib-2.2.0-cp27-cp27m-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl Requirement already satisfied: subprocess32 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: backports.functools-lru-cache in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: pyparsing!=2.0.4,!=2.1.2,!=2.1.6,>=2.0.1 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: cycler>=0.10 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: numpy>=1.7.1 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: kiwisolver>=1.0.1 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: pytz in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: python-dateutil>=2.1 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: six>=1.10 in /usr/local/lib/python2.7/site-packages (from matplotlib) Requirement already satisfied: setuptools in /usr/local/lib/python2.7/site-packages (from kiwisolver>=1.0.1->matplotlib) Installing collected packages: matplotlib Exception: Traceback (most recent call last): File "/usr/local/lib/python2.7/site-packages/pip/basecommand.py", line 215, in main status = self.run(options, args) File "/usr/local/lib/python2.7/site-packages/pip/commands/install.py", line 342, in run prefix=options.prefix_path, File "/usr/local/lib/python2.7/site-packages/pip/req/req_set.py", line 784, in install **kwargs File "/usr/local/lib/python2.7/site-packages/pip/req/req_install.py", line 851, in install self.move_wheel_files(self.source_dir, root=root, prefix=prefix) File "/usr/local/lib/python2.7/site-packages/pip/req/req_install.py", line 1064, in move_wheel_files isolated=self.isolated, File "/usr/local/lib/python2.7/site-packages/pip/wheel.py", line 345, in move_wheel_files clobber(source, lib_dir, True) File "/usr/local/lib/python2.7/site-packages/pip/wheel.py", line 323, in clobber shutil.copyfile(srcfile, destfile) File "/usr/local/Cellar/python@2/2.7.14_3/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 97, in copyfile with open(dst, 'wb') as fdst: IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/matplotlib/legend.pyc'  Basically I had a ownership problem, that can be solve using sudo.  1$ sudo pip install matplotlib



Or fixing the ownership like this:


1

$sudo chown -R$(echo $USER) ~/Library/Caches/pip  Now, I was able to install. ## How to install QGIS 3? Well, this is a little bit more challenging, but just a little bit. The only version of a Homebrew formula that is available to install QGIS 3 is the developer version one that is in this qgis/homebrew-qgisdev repo-tap. So I just have to tap that repo:  1$ brew tap qgis/homebrew-qgisdev



However, I needed to make changes in the formula to be able to install because it has a dependency on Matplotlib on Homebrew/homebrew-science and as we learned before that formula doesn’t exist anymore. In this case, it isn’t like in the QGIS 2, that it builds anyway and then ask you to install Matplotlib. It just doesn’t build and throws an error.

I have two options here. I can just delete or comment the line where the dependency is called, or I can replace it for the legacy formula, which is located in the brewsci/homebrew-science tap. Either way I proceeded in the same way as I did previously.

First, I created a branch and edited the formulae.


1
2
3

$cd /usr/local/Homebrew/Library/Taps/qgis/homebrew-qgisdev$ git checkout -b matplotlib-fix
$brew edit qgis3-dev  You can check how I’ve edited mine. The important part is in the highlighted 86-87 lines. Then, I just committed my edits  1 2$ git add Formula/qgis3-dev.rb
$git commit -m "fix for matplotlib"  Before I tried to build I have to do two more tweaks to be able to compile without errors. First I have to reinstall Bison.  1$ brew reinstall bison



And then I have to modify the file /usr/local/bin/pyrcc5 and change pythonw2.7 to python3.


1
2

#!/bin/sh
exec python3 -m PyQt5.pyrcc_main ${1+"$@"}



Now I could build QGIS 3 developer edition:


1

$brew install --no-sandbox qgis3-dev --with-grass --with-saga-gis-lts  After I finished building the QGIS 3, I moved the app from the Homebrew Cellar to the /Applications folder in the same way I moved QGIS 2, but since I want to keep QGIS 2 and QGIS 3, in the process I renamed the app to QGIS 3.app.  1 2$ mv /usr/local/opt/qgis3-dev/QGIS.app /Applications/QGIS\ 3.app
$ln -s /Applications/QGIS\ 3.app /usr/local/opt/qgis3-dev/QGIS.app  ## Final thoughts I hope that in the near future the situation improve and we can enjoy the last version of QGIS on macOS in a easier way. Perhaps even without needed to compile. However, in this very moment isn’t the case. You have to take into account that with this method you are installing the QGIS 3 developer version, so probably isn’t going to be really stable, or perhaps you are going to have no problem. I guess that you can install the stable version using the QGIS3-dev formulae, you just have to change the values branch => to "release-3_0" in line 37 and version to "3.0" on line 38.  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532 533 534 535 536 537 538 539 540 541 542 543 544 545 546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587 588 589 590 class Qgis3DevUnlinkedFormulae < Requirement fatal true satisfy(:build_env => false) { !qt4_linked && !pyqt4_linked && !txt2tags_linked } def qt4_linked (Formula["qt"].linked_keg/"lib/QtCore.framework/Versions/4").exist? rescue return false end def pyqt4_linked (Formula["pyqt"].linked_keg/"lib/python2.7/site-packages/PyQt").exist? rescue return false end def txt2tags_linked Formula["txt2tags"].linked_keg.exist? rescue return false end def message s = "Compilation can fail if these formulae are installed and linked:\n\n" s += "Unlink with brew unlink qt or remove with brew uninstall qt\n" if qt4_linked s += "Unlink with brew unlink pyqt or remove with brew uninstall pyqt\n" if pyqt4_linked s += "Unlink with brew unlink txt2tags or remove with brew uninstall txt2tags\n" if txt2tags_linked s end end class Qgis3Dev < Formula desc "User friendly open source Geographic Information System" homepage "https://www.qgis.org" url "https://github.com/qgis/QGIS.git", :branch => "release-3_0" version "3.0" option "without-ninja", "Disable use of ninja CMake generator" option "without-debug", "Disable debug build, which outputs info to system.log or console" option "without-qt5-webkit", "Build without webkit based functionality" option "without-pyqt5-webkit", "Build without webkit python bindings" option "without-server", "Build without QGIS Server (qgis_mapserv.fcgi)" option "without-postgresql", "Build without current PostgreSQL client" option "with-globe", "Build with Globe plugin, based upon osgEarth" option "with-grass", "Build with GRASS 7 integration plugin and Processing plugin support (or install grass-7x first)" option "with-oracle", "Build extra Oracle geospatial database and raster support" option "with-orfeo5", "Build extra Orfeo Toolbox for Processing plugin" option "with-r", "Build extra R for Processing plugin" option "with-saga-gis-lts", "Build extra Saga GIS for Processing plugin" # option "with-qt-mysql", "Build extra Qt MySQL plugin for eVis plugin" option "with-qspatialite", "Build QSpatialite Qt database driver" option "with-api-docs", "Build the API documentation with Doxygen and Graphviz" option "with-3d", "Build with 3D Map View panel" depends_on Qgis3DevUnlinkedFormulae # core qgis depends_on "cmake" => :build depends_on "ninja" => [:build, :recommended] depends_on "bison" => :build depends_on "flex" => :build if build.with?

Bottles support only Homebrew's Python3

QGIS is built as an application bundle. Environment variables for the
Homebrew prefix are embedded in QGIS.app:
#{opt_prefix}/QGIS.app

You may also symlink QGIS.app into /Applications or ~/Applications:

To directly run the QGIS.app/Contents/MacOS/QGIS binary use the wrapper
script pre-defined with Homebrew prefix environment variables:
#{opt_bin}/#{name}

NOTE: Your current PATH and PYTHONPATH environment variables are honored
when launching via the wrapper script, while launching QGIS.app
bundle they are not.

For standalone Python3 development, set the following environment variable:
export PYTHONPATH=#{qgis_python_packages}:#{gdal_python_packages}:#{python_site_packages}:\$PYTHONPATH

Anyhow, I think I’m going to keep the 3.1 version for a while.

1. No, you can see that because I deteletd the branch… Sorry.
