Error on install

[willkochtitzky]

Hi, I got the below (and attached) error when I tried install the QGIS plugin on QGIS 3.16.16 on MacOS. Do you have any advice on how to fix this?

An error occurred during execution of following code: import pyplugin_installer

It looks like you have a low version of matplotlib but also old version of QGIS. I suggest you update QGIS and try again.

[willkochtitzky]

Thank you for your reply! I did update QGIS but that didnt fix it. I will look into updating Matplotlib, etc. Thanks, Will

I am a windows user myself, so maybe some more experiences IOS user can help you here, e.g. @sunt05?

[sunt05]

This seems to be a X11 related issue - try this one and see if it works.

[willkochtitzky]

Thanks @sunt05 for the advice! I got it working without problems on another Mac, but even after updating that XQuratz I am still getting errors on that original computer. I have a work around for the moment, thanks! I will try to dig into it more for that first machine. I really appreciate all the help!
