Hi Karel,
I have no idea what's wrong.
If I ask nicely:
:- which python2
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2
:- python2 --version
Python 2.7.18
all seems well.
I have has this problem before and usually I just purge all "brew" versions of python,
and perhaps re-install/update the command line tools from x-code - then all works fine.
Right now my Mac reports my X-code and command line tools as up to date.
When it is checking for python - what is the check? How does it determine "usability"? It's not simple presence of the binary.
Currently I have three python2s:
:- type -a python2
python2 is /Library/Frameworks/Python.framework/Versions/2.7/bin/python2
python2 is /Library/Frameworks/Python.framework/Versions/2.7/bin/python2
python2 is /usr/local/bin/python2
The first one an the $PATH is the one the tool builder doesn't like.
:- type python2
python2 is hashed (/Library/Frameworks/Python.framework/Versions/2.7/bin/python2)
Thanks,
Andrew
