pipx

pipx is a command-line tool that lets you install and run Python-based command-line applications in isolated environments, avoiding conflicts with other Python packages or system dependencies.

Whereas pip installs packages globally or into a virtual environment (which you typically have to manage yourself), pipx automatically creates and manages a separate environment for each installed tool, making it ideal for installing CLI utilities like submit50.

If you don’t already have pipx installed, you can install it for

• Linux

• macOS

• Windows
