pipsi = pip script installer
What does it do?
pipsi makes installing python packages with global entry points painless. These are Python packages that expose an entry point through the command line such as Pygments.
If you are installing Python packages globally for cli access, you almost certainly want to use pipsi instead of running
sudo pip .... so that you get
- Isolated dependencies to guarantee no version conflicts
- The ability to install packages globally without using sudo
- The ability to uninstall a package and its dependencies without affecting other globally installed Python programs
pipsi is not meant for installing libraries that will be imported by other Python modules.
How do I get it?
curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python
to see installation options, including not automatically modifying the PATH environment variable
curl https://raw.githubusercontent.com/mitsuhiko/pipsi/master/get-pipsi.py | python - --help
How does it work?
pipsi is a wrapper around virtualenv and pip which installs scripts provided by python packages into isolated virtualenvs so they do not pollute your system's Python packages.
pipsi installs each package into
~/.local/venvs/PKGNAME and then symlinks all new scripts into
~/.local/bin (these can be changed by
PIPSI_BIN_DIR environment variables respectively).
Here is a tree view into the directory structure created by pipsi after installing pipsi and running
pipsi install Pygments.
/Users/user/.local ├── bin │ ├── pipsi -> /Users/user/.local/venvs/pipsi/bin/pipsi │ └── pygmentize -> /Users/user/.local/venvs/pygments/bin/pygmentize ├── share │ └── virtualenvs └── venvs ├── pipsi └── pygments
pip install --user each
PKGNAME is installed into its own virtualenv, so you don't have to worry about different packages having conflicting dependencies. As long as
~/.local/bin is on your PATH, you can run any of these scripts directly.
Installing scripts from a package:
$ pipsi install Pygments
Installing scripts from a package using a particular version of python:
$ pipsi install --python /usr/bin/python3.5 hovercraft
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.
