What's the Difference Between venv, pyvenv, virtualenv, virtualenvwrapper, pyenv, pipenv, and More?

Distinguishing venv, pyvenv, pyenv, virtualenv, virtualenvwrapper, pipenv, and More

With the introduction of venv in Python 3.3, the landscape of Python environment management tools has become more complex. Let's delve into the differences among various packages that match the pattern (py)?(v|virtual|pip)?env.

PyPI Packages Outside the Standard Library

• virtualenv: A popular tool for creating isolated Python environments for libraries. It modifies the PATH environment variable to include a custom bin directory containing an exact copy of the Python binary.
• pyenv: Manages multiple Python versions, allowing developers to test code against different Python versions. It utilizes special scripts that dynamically determine the Python version to be used based on environment variables or configuration files.
• pyenv-virtualenv: A plugin that integrates pyenv with virtualenv, enabling the use of both tools simultaneously. However, for Python 3.3 and later, it delegates venv creation to python -m venv.
• virtualenvwrapper: A set of extensions for virtualenv, providing convenient commands for creating, listing, and switching between virtual environments.
• pyenv-virtualenvwrapper: A plugin that seamlessly integrates virtualenvwrapper into pyenv.
• pipenv: A tool that combines Pipfile, pip, and virtualenv into a single command-line tool. It uses a hash of the project directory to locate the virtual environment.

Standard Library

• pyvenv: A legacy script shipped with Python 3.3-3.7. Running python3 -m venv produced the same results.
• venv: A package included in Python 3, accessible through python3 -m venv. Similar to virtualenv but with fewer features. virtualenv remains more widely used due to its support for both Python 2 and 3.
