I think the error is quite verbose and tells you everything you need to know.

Generally, do not install packages outside of a virtual environment unless you know what you're doing. Given the option, use your package manager version of the same package. Outside of that, use your python environment manager of choice to install stuff. There are lots of options: conda, uv, venv, virtualenv, pipenv, etc.

The error exists to warn you that you could potentially break critical system installed packages by installing other things at a user or system level with pip.

If you want access to it at system-level, you can use pip install --user .... If you run scripts as your user it'll be as if it was installed as a system package.

Only use that if it's something you use to manage your system. If you're using this as a development environment, use venvs.

It's mostly Debian-focused, but you should probably use venvs. They allow you to have different versions of Python packages for different applications. I especially like it when using it in combination with pythonz for applications that require a different version than the system Python.

I find they prevent the system Python from being a complete pile of anarchy.

Like others have said, the error tells you everything you need to know.

In some Linux distributions it blocks you from installing system packages via pip, often there are then packages which can be installed via your distros package manager.

With arch for example:

sudo pacman -S python-'package'

Or, as others mentioned using venv.

The error message is very detailed and there is nothing to add to it.

If you want to install an application/CLI tool, use pipx or your system package manager. If you want to install a library, use a virtual environment (e.g. by using python -m venv) or your system package manager.

If you're tired of python's and venv issues, give miniconda a try. It solved most of my issues with dependencies and different python version in scripts.

It's probably a skill issue regarding to pip/pipx/venv... But miniconda really made everything easier.

We enjoyed Wicked. We’ve seen it a few times and it was a solid performance, plus the theatre has good popcorn :)

We stayed in White Chapel and discovered too late that the area around our hotel (Aldgate East station) had some awesome little local restaraunts and a really cool indoor-ish open air shopping center of small businesses. Was neat!

The Hydrant on monument st had solid beer selection.
