I am very new to python and on stackoverflow, so please be indulgent with my questions. I had successfully installed matplotlib with the command pip install matplotlib without any errors and I tried to import it with the command:

import matplotlib

here is the text code error

and I also see this msg:

ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/PIL/_imaging.cpython-310-darwin.so, 2): Library not loaded: @loader_path/libXdmcp.6.dylib
  Referenced from: /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/PIL/.dylibs/libxcb.1.1.0.dylib

I expected to have no issues

For information : i am on macOS 10.14.6 (Mojave)

According to this case in github. This is an issue about pillow instead of matplotlib.

You can use the following way to install Pillow:

1. download .zip file and extract it.
2. use command cd path\you\download\file
3. uninstall the current Pillow with python3 -m pip uninstall Pillow or python -m pip uninstall Pillow
4. install from this new wheel with python3 -m pip install Pillow-9.4.0-1-cp310-cp310-macosx_10_10_x86_64.whl

You can also install .whl file directly then use command python3 -m pip install Pillow-9.4.0-1-cp310-cp310-macosx_10_10_x86_64.whl to install it.
