On My Mac I've downloaded Sage 9.4 which has Python 3.9 and put it into my Applications folder after extracting. However, when I try to run a script using a shebang with the path to Python3.9 I have a problem with a binary_pkg that can't be found to run Python 3.9 in the Sage package.
the error message is
dyld: Library not loaded: /Users/buildbot-sage/slave/binary_pkg/build/source/SageMath/jc4b6yulaujayb9sr94ia88eourzeqip0oidmas3/local/lib/libpython3.9.dylib
Running a script worked for earlier Sagemath packages using Python2.7. Does anyone understand this?
