I've found that venv's work. They're just very inconvenient (having to constantly manage which venv you're in when you change directory). Consider that with NPM, only two of those commands are ever needed:

    # install the requirements
    npm install

    # remove it
    rm -rf node_modules

The rest is unnecessary because NPM uses the equivalent of a venv automatically based on your current working directory and the location of your package.json file.
