Describe the bug

After Updating the azure-cli on the Mac (Version 11.4) with brew upgrade I got the following error messages.

❯ az vm list
/usr/local/Cellar/azure-cli/2.26.0/libexec/bin/python: No module named azure.cli.__main__; 'azure.cli' is a package and cannot be directly executed

or while finding module specification for 'azure.cli' (ModuleNotFoundError: No module named 'azure')

So I was playing with different Python Versions etc. But nothing helped.

So I was going to install the python modules myself:

pip install azure.cli
pip install azure

Error output

But now everything works as expected.

To Reproduce

brew update && \
brew upgrade azure-cli &&  \
brew install python3 && \
 brew upgrade python && \
brew link --overwrite python3 && \
brew link --overwrite  azure-cli 

Expected behavior
brew upgrade should not brake azure-cli

Environment summary

• MacOS 11.4
• Python: Python 3.9.6
• Azure-CLI: 2.26.0
• PIP: pip 21.1.3 (python 3.9)
• HomeBrew

Additional context
I don't know why the azure-cli broke, however I believe a custom python version was included (but am unsure), however now the python is set as symlink.
