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

[William Kyngesburye]

That was just a test, only one python module.

So, now it looks like pip is working in the Terminal, but not in my installers.  Try running the GDAL Complete installer again, but don't close it when it finishes.  Instead, open the Installer Log from the Window menu (in the installer).  Then use the popup menu to Show All Logs.  There should be some lines with "postinstall:", what do these say?
