Errors with environment markers

Great tool but seems it does not work with environment markers in requirements files:

Any chance to get support for this pip feature?

Hi, yes, I'll try to implement support for these markers soon :) Thanks

+1, same for the support for Python versions like:

pytest==7.0.1; python_version=="3.6"
pytest==7.1.2; python_version>="3.7"
pytest-mock==3.6.1; python_version=="3.6"
pytest-mock==3.7.0; python_version>="3.7"

Currently it crashes on

Error while parsing package pytest-mock==3.6.1; python_version=="3.6" (skipping).
