import matplotlib.pyplot as plt fails

[dershow]

I have py39-matplotlib port installed. When I then try:

>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/matplotlib/pyplot.py", line 55, in <module>
    from matplotlib import rcsetup, style
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/matplotlib/style/__init__.py", line 1, in <module>
    from .core import available, context, library, reload_library, use
  File "/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/matplotlib/style/core.py", line 26, in <module>
    import importlib_resources
ModuleNotFoundError: No module named 'importlib_resources'

I found a work around:

sudo port install py39-importlib-resources

Perhaps this should be a dependent?

sorry for the trouble and thanks for reporting!

I never noticed this as many other packages have importlib-resources as a dependency so many people will have this already. But yes, you are correct that it should be a dependency; it's just a little strange to me that they have only listed it under extra_requires, which typically means it's only needed for certain additional features and not needed for "normal" usage. However, from looking at the documentation it looks like that is not their intention. Of course, it's also possible that I am misunderstanding the intended usage of extra_requires. Nevertheless, I will add it as a dependency shortly and push the change.
