What is the difference between venv, pyvenv, pyenv, virtualenv, virtualenvwrapper, pipenv, etc?
To create isolated Python environments, use venv—python3 -m venv myenv activates myenv. virtualenv offers a broader feature set for any Python version. pyenv is the perfect tool for managing multiple Python installs. Enjoy enhanced virtualenv management with virtualenvwrapper. pipenv simplifies dependency management with a Pipfile. But skip pyvenv, it's outdated.
Here's how to activate an env with venv:
Understanding environments and tools
Python environments ensure that your project's dependencies don't create a series of unfortunate events elsewhere on your machine. The tools venv, virtualenv, pyenv, virtualenvwrapper, and pipenv assist in managing these environments.
venv: Python's built-in environment manager
A core component of Python 3.3 and onwards, venv creates a self-contained environment with a clean Python binary and its own pip utility. That's a lot of responsibility for a venv!
pyenv: Juggling Python versions made effortless
If you're striving for peace among multiple Python versions, pyenv is your mediator. It makes switching between different versions a breeze.
virtualenvwrapper: Making environment control a cakewalk
Featuring powerful commands to manage your Python environments, virtualenvwrapper provides easy environment setup. A godsend for developers working with multiple environments.
pipenv: Harnessing the power of Pipfile
pipenv is your knight in shining armor for modern Python applications. Combining virtualenv and pip features, it uses a Pipfile and Pipfile.lock for deterministic builds.
virtualenv: Still relevant after all these years
Although virtualenv may seem like the old guard in this comparison, it supports Python 2.7 and brings additional features not found in venv.
Code it right!
Here are some practical scenarios that will help you code smarter, not harder!
Maintaining Python version sanity with pyenv
Let's say you're working in a team and want to normalize the Python versions across the board (or spacetime continuum, if you're into that). Well, pyenv makes that process smoother than a freshly depilled cat.
Deploy like a boss with pipenv
Deployment processes can be as messy as trying to herd cats. But with pipenv, you can use Pipfile and Pipfile.lock to ensure secure and efficient deployment. In other words, you'll be herding those cats like the best of them!
Legacy support? virtualenv has your back
Suppose you're stuck with an old project that still clings to Python 2.7. Using virtualenv, you can work on these antique pieces while safeguarding the system Python from any potential issues. It's like putting a cozy bubble around your code.
venv for the minimalist coder
If you favor simplicity and speed above all else, here's some good news: venv provides an accessible interface out of the box. You'll have an isolated environment faster than you can say "ImportError: No module named setuptools"!
