pipsi

pipsi is an older Python command-line tool for installing Python packages that expose global scripts. Its name stands for “pip script installer.” Instead of installing command-line packages into the system Python environment, it places each package into its own isolated virtualenv. It then symlinks the installed scripts into a user-level binary directory, allowing commands to run globally without using sudo. This design helps avoid dependency conflicts between unrelated Python command-line tools. The project is no longer maintained and now points users toward pipx as the actively maintained successor.
