[BUG] Cannot install importlib as it's a builtin package

[LeiWang1999]

Hi all, I'm trying to build this project from source, however the build pipeline is falling at pip install -r requirements:

pip install importlib>=1.0.4
  error: subprocess-exited-with-error
  
  × python setup.py egg_info did not run successfully.

  note: This error originates from a subprocess, and is likely not a problem with pip.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

It seems that the importlib shouldn't be installed manually, as it's a built in lib from python 3.1.
