Prevent installation with pip when not in virtual environment

[ns-rse]

Random I came across to prevent installing anything with pip outside of a virtual environment.

pip config set global.require-virtualenv True

Creates the file ~/.config/pip/pip.conf with the contents

[global]
require-virtualenv = True

And pip should then complain if you try to pip install outside of a virtualenv.

Apparently you can set the PIP_REQUIRE_VIRTUALENV=true in your .zshrc or .bashrc too.

I wonder if there is similar to prevent installation in the base conda environment. 🤔
