PYENV and Python 3.8.10 Install

Install PyEnv

• Use pyenv to Install Python 3.8.

# Maybe optional xcode -> xcode-select --install
# Maybe optional homebrew -> /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew update
brew install openssl readline sqlite3 xz zlib
brew install pyenv

Update bash profile

Now add this to your shell profile (for me .zszchrc)

# Pyenv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"
