Last week I decided to finally upgrade my macOS BigSur to Sonoma. As usual I get issues after the upgrade. For example, security settings, apps permissions, custom backup script I put together to backup my files to a NAS drive stop working. This time I got error “Python3.9: bad interpreter: No such file or directory“.
I usually play around with Docker for personal projects and to improve my skills. I was working on a Python/Flask/SQLAlchemy app and decided to use my native python instead of creating another container in Docker. To solve the error above I did the following: (after brewing a great cup of coffee from Peru at home of course!)
- Installed Homebrew
- After installing Homebrew I ran: brew install pyenv
Next, you can use pyenv to manage your python versions – Very cool! Use the below command for example:
pyenv install 3.9.2 If you desire a different version do:
pyenv install 4.x.xRemember, you need to have macOS Xcode/Developer tools installed on your mac before having Homebrew.
Final steps – Update your bash_profile(I still use bash instead of zsh – yes!):
echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profileecho 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profileIf you do not have a /bin directory in your pyenv_root folder (you may only have a /shims directory) you may need to instead run this version of the command:
`echo 'export PATH="$PYENV_ROOT/shims:$PATH"' >> ~/.bash_profile`Add pyenv to your Terminal:
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bash_profileAnd finally, reset your Terminal:
