Example: How to install a specific version of python3 on OS X

Since switch has been removed from brew, we proceed as follows ...

Install the desided version:

brew install python@3.8

List available versions:

brew list | grep python

    python@3.8
    python@3.9

Change versions:

brew unlink python@3.8
brew unlink python@3.9
brew link --overwrite python@3.8

Check:

python3 --version

    Python 3.8.7

Then you might also want to reinstall virtualenvwrapper for the new active Python interpreter:

pip3 install virtualenvwrapper

If this doesn't work due to "error: externally-managed-environment", try the following:

pip install virtualenvwrapper --break-system-packages

List existing versions of a formula (example)

brew search '/^redis$|^redis@/'
    ==> Formulae
    redis ✔     redis@3.2     redis@4.0    redis@6.2

or, lookup into detailed info:

brew info --json redis
