What Python Environment Management Tools (venv, virtualenv, pyenv, etc.) Should I Use and When?

Understanding Python Environment Management Tools: venv, pyvenv, pyenv, and More

Python offers various tools for creating isolated environments for Python libraries. Understanding the differences between these tools is essential for choosing the best option for your project.

Standard Library Tools

pyvenv: A script included in Python versions 3.3 through 3.7, it is similar to using python3 -m venv. However, pyvenv is no longer available in Python 3.8 due to issues.

venv: Introduced in Python 3, venv creates isolated environments like virtualenv but lacks some of its features. It is primarily recommended for creating simple isolated environments, while virtualenv remains more popular due to its support for both Python 2 and 3.

PyPI Packages

virtualenv: A widely used tool for creating isolated Python environments. It works by modifying the PATH environment variable to include a custom bin directory where Python commands are located. Python libraries are installed relative to the environment directory, providing isolation.

pyenv: A tool designed to manage different Python versions. It allows you to switch between various Python versions by modifying the PATH environment variable. pyenv simplifies the process of installing and managing multiple Python versions.

pyenv-virtualenv: A plugin for pyenv that allows you to use pyenv and virtualenv simultaneously. It can automatically run python -m venv if available instead of virtualenv.

virtualenvwrapper: Adds functionality to virtualenv, providing commands for creating, listing, and switching between virtualenv environments. This is useful for managing multiple virtualenvs.

pyenv-virtualenvwrapper: A plugin for pyenv that integrates virtualenvwrapper's features into pyenv.

pipenv: Combines Pipfile, pip, and virtualenv into a single command-line tool. It creates virtualenv environments for developing Python applications, placing them in a specific directory based on the project path.

Recommendation for Beginners

For beginners, it is recommended to start with learning virtualenv and pip, which are compatible with both Python 2 and 3 and provide essential environment management capabilities. As your needs grow, you can explore other tools.
