Multiple Python versions

Because one does not simply mess with MacOS default Python

Install Homebrew

Homebrew is a package manager for MacOS, must have CLI utility.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

MacOS comes with a python version but you should install the latest stable version of python.

 brew install python

Download the get-pip file

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Now run this file to install pip

python get-pip.py

sudo ln -s -f /usr/local/bin/python3.9 /usr/local/bin/python

pyenv makes it easy to install, manage, and switch between multiple Pythons versions.

brew install pyenv

pyenv install 3.9.4
pyenv install 2.7.16

pyenv global 3.9.4

pyenv versions
python -m venv venv
source ./venv/bin/activate
(venv) $ which python

To exit the virtual environment
