Unversioned and major-versioned symlinks `python`, `python3`, `python-config`, `python3-config`, `pip`, `pip3`, etc. pointing to
`python3.9`, `python3.9-config`, `pip3.9` etc., respectively, are installed into

You can install Python packages with
    pip3.9 install <package>

    brew install python3
