[Qgis-user] QGIS 3 errors after install on macOS 10.13.4

[William Kyngesburye]

The latest pip, as used to install Python modules, has a problem that affects some people.  I haven't figured out a definite solution, but there is a workaround that means manually installing all the python modules.  Or you can wait for QGIS 3.0.3 - at least I'll use the workaround in the installers.

You can help me with some information:

- what version of Python did you install?  specifically, which system version?  Starting with Python 3.6.5, there are now 2 installers: one for older OS X systems, it has "macosx10.6" in the installer name (this is how all previous versions were built), and one for newer systems, it has macosx10.9 in the installer name.

- which version of pip is installed?  you can check from a Terminal with:

  pip3 -V

- your macOS version

I found a thread that has a similar error, and the fix was to reinstall all the components, but I’ve done this a few times now to no avail (both overwriting QGIS3.app and after deleting it). I’ve also set $PATH to prepend "/Library/Frameworks/Python.framework/Versions/3.6/bin:/Library/Frameworks/GDAL.framework/Versions/2.2/Programs:” in the environment settings.
