Hi,

the 2 commands helped, however I had to do two more (maybe my specific usecase, not sure since I’m new into this):

sudo install_name_tool -change "@rpath/libc++.1.dylib" "/usr/lib/libc++.1.dylib" /Library/Python/2.7/site-packages/numba/typeconv/_typeconv.so
sudo install_name_tool -change "@rpath/libc++.1.dylib" "/usr/lib/libc++.1.dylib" /Library/Python/2.7/site-packages/numba/_dispatcher.so

Thanks a lot for all your help!

OK, after trying a bunch of things and being shot down by System Integrity Protection, this is the best workaround we can come up with.

Assuming you are seeing the library open error for the exact path /Library/Python/2.7/site-packages/llvmlite/binding/libllvmlite.dylib, you should do the following:

sudo install_name_tool -change "@rpath/libz.1.dylib" "/usr/lib/libz.1.dylib" /Library/Python/2.7/site-packages/llvmlite/binding/libllvmlite.dylib
sudo install_name_tool -change "@rpath/libc++.1.dylib" "/usr/lib/libc++.1.dylib" /Library/Python/2.7/site-packages/llvmlite/binding/libllvmlite.dylib

Note that this fix will need to be repeated if you reinstall llvmlite, and this should not be needed for any Python other than the Python shipped by macOS.

Moving forward, we’re going to see if we can get this fix applied automatically when we build the wheel.
