Rather than using the ‘pip’ installable mod_wsgi, you might want to try older
way of building it from source code.
Grab down latest source tar ball from:
https://github.com/GrahamDumpleton/mod_wsgi/releases
<https://github.com/GrahamDumpleton/mod_wsgi/releases>
When unpacked, build it using:
./configure —with-python=/some/path/to/canopy/bin/python
make
Before trying to install it, run:
otool -L src/server/.libs/mod_wsgi.so
If that doesn’t show the Python library resolving, try instead:
make distclean
./configure —with-python=/some/path/to/canopy/bin/python --enable-framework
make
Run otool again. Does that then show it as resolving?
