Installation error: No matching distribution found for matplotlib~=3.8.0

Hello! I am trying to install species on another machine (where I do not have sudo rights) and get:

[…]/species$ pip install -e .
Defaulting to user installation because normal site-packages is not writeable
…  # many things that get installed without problem

I have Python 3.8.10. [I get the same error on my computer, actually, but had already installed species before the requirements got increased (my computer got grandfathered in :smile:).] What can I do?

[gabrielastro]

One "solution" was to upgrade python to 3.10 instead of python 3.8.10… I might not be able to do this on every machine but at least it avoids the problem (hence the quotation marks around "solution" :wink:).

Yes! species is only compatible with Python 3.9/3.10/3.11: https://species.readthedocs.io/en/latest/installation.html

As a Python manager, I could recommend pyenv: https://github.com/pyenv/pyenv

And best to use a virtual environment to avoid conflicting versions of dependencies from other packages.

Ah! Sorry! I had not read that page recently and last time, 3.8 was still compatible :). Thanks for the tip about pyenv!
