1. Install

Install isort using your preferred Python package manager:

pip3 install isort

OR

poetry add isort

OR

pipenv install isort

OR

For a fully isolated user installation you can use pipx

pipx install isort

Tip

If you want isort to act as a linter for projects, it probably makes since to add isort as an explicit development dependency for each project that uses it. If, on the other hand, you are an individual developer simply using isort as a personal tool to clean up your own commits, a global or user level installation makes sense. Both are seamlessly supported on a single machine.
