PvP - The Ultimate Python Virtualenv and Package Manager
Python package manager to end all Python package managers
Python virtualenv and Pip (PvP) manager is a modern, standards-compliant, fast, beautiful package manager created with love.
Also, it's a very small shell script.
What's not to like?
Installation
Get it directly from the source:
git clone [email protected]:senko/pvp.git
cd pvp/
Copy the script somewhere in your $PATH.
If you're on a modern Linux distribution:
cp pvp ~/.local/bin
chmod a+rx ~/.local/bin/pvp
or to install for all users (should work on both Linux and MacOS):
sudo cp pvp /usr/local/bin/
sudo chmod a+rx /usr/local/bin/pvp
Add the contents of pvp-bashrc to your shell startup script (most likely ~/.bashrc unless you're one of the cool kids and use Zsh, in which case it's probably .zshrc).
Re-enter the shell or source your shell startup script and you're ready to go!
Usage
Initialize a Python virtual environment in the current directory:
pvp init
Install packages:
pvp add pkgname otherpkgname
Remove packages:
pvp rm pkgname
See the list of installed packages:
pvp list
Activate a Python virtual environment that's been initialized in the current directory or any of its ancestors:
pvp
Deactivate a Python virtual environment, if it's activated:
deactivate
Run Python within virtual environment without activating it for the current shell:
pvp run manage.py runserver
How it works
Oh, how it actually works?
It uses the awesome pip and venv modules from Python 3 standard library and a little bit of shell scripting to make using them easier.
PvP will figure out the virtual environment you're in based on your current directory. It searches for .venv sub-directory in the current directory, then the parent directory, then its parent, all up to /.
The first .venv directory that is found will be used. If none are found, PvP assumes it's not running in a project that has a virtual environment set up.
This is similar what npm does when searching for node_modules.
Curious minds are invited to check the source. It's a pretty short read.
Contributing
If you've found a bug, problem, security issue, have an idea, suggestion, comment, or just want to rewrite it in Rust for speed and memory safety, I've just got two rules:
- Bug reports and patches are more than welcome
- I don't guarantee I'll fix anything or merge any patches you send
But it doesn't do X!
Listen, I understand. I really do. Have you tried using pipenv, Poetry, conda, PDM, homebrew, apt, rpm, or writing your own?
It's really a rite-of-passage for every serious Python developer, you know.

MIT. Gee, I do hope Amazon doesn't fork this and make an AWS product out of it.
Is this a joke?
Obviously. I use it every day.
