InvalidRequirement: name@ git+...@branch; (python_version=="...") and extra == "..." #432
Description
Hello. I found a requirement that packaging deems invalid but I am not sure why.
This is happening on 20.4, 20.9 and main branch @ 7350746.
I see what I believe is a proper requirement generated by https://github.com/sqlobject/sqlobject/blob/3.9.1/setup.py#L118-L121 as:
[oursql:python_version=="2.7"]
oursql@ git+https://github.com/sqlobject/oursql.git@master
[oursql:python_version>="3.4"]
oursql3@ git+https://github.com/sqlobject/oursql.git@py3k
Parsed by importlib.metadata.PathDistribution.requires as:
oursql@ git+https://github.com/sqlobject/oursql.git@master; (python_version=="2.7") and extra == "oursql"
oursql3@ git+https://github.com/sqlobject/oursql.git@py3k; (python_version>="3.4") and extra == "oursql"
Failing with:
>>> from packaging.requirements import Requirement
>>> Requirement('oursql@ git+https://github.com/sqlobject/oursql.git@master; (python_version=="2.7") and extra == "oursql"')

What's wrong with this requirement?
