It appears that the QGIS 3 installation on macOS does not install the needed python modules for some (many? all?). Something changed in the Python 3 installation at some point where some modules now need distutils to install (or new versions of the modules now use distutils, I didn't get far enough to figure that out). The Mac Python 3 package does not include distutils, but the latest pip does have it as a dependency (older pip versions apparently did not).
So, please make sure when installing Python 3 to use the standard/default install, which installs pip, which then installs distutils. If you have already installed Python 3, install it again to upgrade pip, or upgrade pip from a Terminal (as an admin user): sudo pip3 install --upgrade pip ----- William Kyngesburye <kyngchaos*at*kyngchaos*dot*com> http://www.kyngchaos.com/ Earth: "Mostly harmless" - revised entry in the HitchHiker's Guide to the Galaxy _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
