H3 Package not Installed Automatically on MacOS

[minus34]

Tried to upgrade to the latest Snowflake Connector plugin version (0.11.0) and got the error below in QGIS:

The workaround is to install the package before upgrading using: /Applications/QGIS.app/Contents/MacOS/bin/python3.9 -m pip install h3

Couldn't load plugin 'qgis-snowflake-connector' due to an error when calling its classFactory() method

ModuleNotFoundError: No module named 'h3'

Hey @minus34 we can't reproduce neither this, not this your issue, and both look very similar. Could these issues appear because you have a custom Python version in your QGIS? Can you remove QGIS, install it from scratch and see if it's still reproducible?

[minus34]

Hi @sfc-gh-obielov, have tried both latest release and LTS version of QGIS - both had the same error after clean installs.

Process taken to create error was:

• Delete QGIS.app from $HOME/Applications
• Delete $HOME/Library/Application Support/QGIS folder
• Install QGIS
• Run QGIS, create new project
• Install Snowflake Connector Plugin (v0.11.0) from Plugins menu

Whilst I have admin level privilages - my Macbook has a corporate profile that controls and limits various things. I can't think what might prevent package prerequisites from not being installed automatically, but I can't think of anything else that's special about my setup.

If it can't be replicated, happy for this and #54 to be closed due to the above.

[sfc-gh-obielov]

@minus34 This should be fixed in 1.0.2. Please install it and let me know if you still face the issue

Same failure as #54 on my work MacBook.

Same conclusion - have tested on my personal MacBook (same MacBook & macOS version as my work MacBook) and it installed fine.

Conclusion is that my work's always on proxy (Netskope) is somehow interfering with Python packge installs even though my work MacBook is configured to allow package installs (command line package installs work fine). Another possibility is our malware scanners are blocking it.
