pundler

That’s a great idea. I’ve just been playing with the implementation from the PEP, and it makes things really easy. The speed of simply extracting a bunch of wheels directly in to `__pypackages__/$PYVER/lib/` is a huge benefit. It behaves well if you symlink from a global tree of extracted packages too, like an even simpler version of pundler¹. If others want to play with it without too much breakage, I massaged the patch on to 3.7². The 3.8 base was a little too big a change for my liking ;) 1. https://github.com/Deepwalker/pundler 2. https://gist.github.com/JNRowe/502f8772861cdd21bff5144c416e4... Edit: It’s a third of a second to stand up a complete environment with 63 wheels in its dependency tree for the project I'm playing with right now.

Hey, I have wrote Pundle to solve this problem! Idea is simple — we just have package to install other packages with versions freeze. Pundle maintaine frozen.txt alongside with requirements.txt. What more — pundle does not use virtualenv and install all packages to user directory ~/.Pundledir and import frozen versions on demand. It have all nice commands like install, upgrade, info etc Check it https://github.com/Deepwalker/pundler

But technically no. Virtualenv is quite different, both in scope and approach. https://github.com/Deepwalker/pundler is more similar to bundler
