Answer 1

npm install is complaining that it cannot find python in the environment. To confirm that is the case run the following command

python --version

You should get a command not found exception. To resolve install python after which running the above command will tell you the version of python installed. Some versions of python have a slightly different binary name for example python3 so I recommend you install pyenv which can be used to manage multiple versions of python. Follow the instructions in the README to install pyenv and python. Once the previous command returns the python version you can then try 'npm install' again.

Answer 2

The issue is the missing default python in macos 12. Npm actually tells you

env: python: No such file or directory

To fix this you need to create a python symlink like so:

For homebrew installed python3:

ln -s "$(brew --prefix)/bin/python"{3,}

For any python3:

ln -s "$(which python3)"{3,}
