macOS - Installing Python with Brew and pyenv

In this example, we will update Python 3.9.1 (Mac-supported) to Python 3.10.5 (Pyenv-supported)

Install pyenv

brew install pyenv

2. Use pyenv to install the Python version you want

pyenv install 3.10.5

2.1 Change Python version

pyenv versions
* system (set by /Users/devtooler/.pyenv/version)
  3.10.5

verify the current active version

pyenv global 3.10.5
pyenv versions
  system
* 3.10.5 (set by /Users/devtooler/.pyenv/version)

Change Python version and verify new version

3. Update zsh shell, you will still need to update zsh in order for pyenv to have an affect from the shell

python3 --version
Python 3.9.1

before updating zshrc

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(pyenv init -)"' >> ~/.zshrc

source ~/.zshrc
python3 --version
Python 3.10.5

after updating zshrc
