Python ​

Install with pyenv ​

pyenv install 3.11
pyenv global 3.11

pyenv install 3.11
pyenv global 3.11

You might want to install other versions too

Virtual Environments ​

It's often useful to create virtual environments for projects, so you don't install packages to the global environment.

Creating a virtualenv ​

Example of creating a venv named my-venv with python version 3.11

pyenv virtualenv 3.11 my-venv

pyenv virtualenv 3.11 my-venv

To use this virtualenv in your project, run the following in the project directory

pyenv local my-venv

pyenv local my-venv

This creates a .python-version file. The .bashrc file I use initializes pyenv-virtualenv to automatically activate the virtualenv when you cd into the project directory.

To see what venvs are currently created in the system, run

pyenv virtualenvs

pyenv virtualenvs

To delete a virtualenv, run

pyenv uninstall my-venv

pyenv uninstall my-venv
