pipsi = pip script installer
What does it do? pipsi is a wrapper around virtualenv and pip which installs scripts provided by python packages into separate virtualenvs to shield them from your system and each other.
In other words: you can use pipsi to install things like pygmentize without making your system painful.
How do I get it?
curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python
How does it work?
pipsi installs each package into ~/.local/venvs/PKGNAME and then symlinks all new scripts into ~/.local/bin.
Installing scripts from a package:
$ pipsi install Pygments
Uninstalling packages and their scripts:
$ pipsi uninstall Pygments
Upgrading a package:
$ pipsi upgrade Pygments
Showing what’s installed:
$ pipsi list
How do I get rid of pipsi?
$ pipsi uninstall pipsi
How do I upgrade pipsi? With 0.5 and later just do this:
$ pipsi upgrade pipsi
On older versions just uninstall and reinstall.
