I guess these should be uncommented?

The same file has requests>=2.20.0 and pyyaml>=4.2b1 below which may lead to double requirements issues. 🤔

It seems that in the recent pip, the main function was moved from pip._internal.init to pip._internal.main. It's not the best idea to rely on such internal functions, but I'd say there's a simpler way to fix this without restrictions on pip version

try:
    from pip import main as pip_main
except:
    try:
        from pip._internal.main import main as pip_main
    except:
        from pip._internal import main as pip_main

Yeah this is good observation! I should have looked into this. Though I'm not sure for now how to write tests for this. 😅
