$ pipx install grip
Fatal error from pip prevented installation. Full pip output in file:

pip seemed to fail to build package:
    docopt>=0.4.0

Some possibly relevant errors from pip install:
    error: subprocess-exited-with-error

Oh I forgot to add, for anyone who hits this error:
apt install python3-docopt
python3-docopt is already the newest version (0.6.2-6).

To me, using pipx for CLI tools is better for every python package that is not in repos (Main, Extra, AUR) or not updated, in Arch Linux I get:

$ pip install grip
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try 'pacman -S
    python-xyz', where xyz is the package you are trying to
    install.

    If you wish to install a non-Arch-packaged Python package,
    create a virtual environment using 'python -m venv path/to/venv'.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip.

    If you wish to install a non-Arch packaged Python application,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. Make sure you have python-pipx
    installed via pacman.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

Maybe you get something similar in other distros.
With pipx install everything, simple and easy, because venv.
