I recently installed a package that only runs with python2.7. Within this package, qhull is imported by
import matplotlib._qhull as _qhull
which leads to getting this error
ImportError:dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/_qhull.so, 2): Library not loaded: /opt/local/lib/libqhull.8.0.dylib
Referenced from: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/_qhull.so
Reason: image not found
I have reinstalled qhull by brew, but I still get the above error. I have checked /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/ and _qhull.so* was there.
I have checked brew doctor and didn't get any complaint regarding qhull. Library qhull can be found in /opt/local/lib/ on my system. I also run
python2.7 -m pip install --upgrade matplotlib
to make sure that my matplotlib is upgraded.
As I mainly work with Python3, I would look for a solution that does not cause any changes to my python3 configuration. Do you have any suggestions on solving this problem?
