After installing different python versions using pyenv, and setting the global flag to the version you want to use at the time..

Does this t cause 'pip install modulename' to install only for that version of python or will it instead be useable for ALL installed python versions?


If the latter, and if you want to install a module only for only one particular version of python, then you have to create a virtual environment?
