Installation on Big Sur fails obspy-runtests

Brand-new macbook pro - installed python3 using Homebrew, then followed the instructions here verbatim

except that I specified python=3.8 instead of python=3.7 when creating the environment.

obspy-runtests produces 86 errors, most having to do with matplotlib, but some also with UTCdatetime. The report is here.

Attempts to install by pinning to earlier versions of matplotlib have been unsuccessful. Any suggestions would be most welcome!


Hi Lara, welcome to the forum!

I know that the UTCDateTime tests are fixed in the master branch and can be ignored without hesitation.
I think the same holds true for the matplotlib errors.
