FWIW, for the case of installing Python packages as runnable tools (as opposed to importable libraries), pipx is solid. For example, you can install oscclip to a temp dir with a dedicated venv and run it immediately: $ pipx run --spec 'oscclip @ git+https://github.com/rumpelsepp/oscclip' osc-copy --help Or install it more permanently: $ pipx install 'oscclip @ git+https://github.com/rumpelsepp/oscclip' My own Zsh frontend for managing Python venvs and deps, zpy, makes use of pip-tools to accomplish the same, with its pipx clone, pipz: $ pipz runpkg 'oscclip @ git+https://github.com/rumpelsepp/oscclip' osc-copy --help $ pipz install 'oscclip @ git+https://github.com/rumpelsepp/oscclip'
