A Weird Python Command Not Found Problem
I met a weird problem with the following output:
$ python
pyenv: python: command not found
The `python' command exists in these Python versions:
3.9.11
Note: See 'pyenv help global' for tips on allowing both
python2 and python3 to be found.
What happened??? I just took a nap and turned my computer back on, why did python get lost???
Ok... Let me check these paths:
/usr/bin and /usr/local/bin :$ ls /usr/bin /usr/local/bin | grep python
python3
OMG! ONLY
python3 EXISTS!At that moment, I started to recall if I did anything stupid which removed the system
python by mistake. After half an hour of useless attempts, it flashed through my mind that I had just upgraded to macOS Monterey 12.3.1 before I went to sleep, and let me check the release notes:
PythonDeprecations
Now the truth is out, Apple took a shot at me.
This problem can be fixed simply as I have had another python3 installed by Homebrew.
$ brew install python3
-- snip --
Warning: [email protected] 3.9.12 is already installed and up-to-date.
To reinstall 3.9.12, run:
brew reinstall [email protected]
And now you can simply create a symbolic link to it by:
sudo ln -s /opt/homebrew/bin/python3 /usr/local/bin/python
Finally, try
python again:$ python
Python 3.9.12 (main, Mar 26 2022, 15:44:31)
[Clang 13.1.6 (clang-1316.0.21.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Maybe I should read every release note carefully before I click UPGRADE NOW.
