You could create a zip of the contents of site-packages and add that your PYTHONPATH. Look for the metadata.json, in the dist-info directory { "requires": [ "chardet (>=3.0.2,<4)", "idna (>=2.5,<3)", "urllib3 (!=1.25.1,<1.26,!=1.25.0,>=1.21.1)", "certifi (>=2017.4.17)" ] } which I see isn't in all dist-info dirs. You could also look at pip download --no-binary ':all:' --src src requests It will download the source archives for those package and its deps. I think what you want is within reach. My email is profile, feel free to ask questions.
