Pyenv

Popular Python version management tool. Pyenv allows you to easily install and switch between multiple Python versions on the same machine.

Source: https://github.com/pyenv/pyenv

Installation in Kali

Check out Pyenv where you want it installed. A good place to choose is $HOME/.pyenv (but you can install it somewhere else):

1	`git clone https://github.com/pyenv/pyenv.git ~/.pyenv`

Optionally, try to compile a dynamic Bash extension to speed up Pyenv. Don't worry if it fails; Pyenv will still work normally:

1	`cd ~/.pyenv && src/configure && make -C src`

Define environment variable PYENV_ROOT to point to the path where Pyenv will store its data. $HOME/.pyenv is the default. If you installed Pyenv via Git checkout, we recommend to set it to the same location as where you cloned it.

1	`echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc`

Add the pyenv executable to your PATH if it's not already there

1	`echo 'command -v pyenv >/dev/null \|\| export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc`

run eval "$(pyenv init -)" to install pyenv into your shell as a shell function, enable shims and autocompletion

1	`echo 'eval "$(pyenv init -)"' >> ~/.zshrc`

Then, if you have ~/.profile, ~/.bash_profile or ~/.bash_login, add the commands there as well. If you have none of these, add them to ~/.profile. No need in this case, where we have ~/.zshrc.

If you wish to get Pyenv in noninteractive login shells as well, also add the commands to ~/.zprofile or ~/.zlogin.

Basic usage

Install the desired Python versions using pyenv:

1	`pyenv install 3.9.0`

See installed versions:

1	`pyenv versions`

Set global python version:

1	`pyenv global 2.7.18`
