If an exception occurs when executing a command, I executed it again in debug mode (

Issue
I have a case very similar to #2802 where I am installing a vendored wheel file and it the code that generates PKG-INFO is producing an invalid line.
$ poetry add --platform linux blob/pyvcam-2.1.0-cp39-cp39-linux_x86_64.whl
results in pyproject's dependencies having:
pyvcam = {path = "blob/pyvcam-2.1.0-cp39-cp39-linux_x86_64.whl", platform = "linux"}
and during a tox run the following error:
...snip...

raise RequirementParseError(str(e))
pip._vendor.pkg_resources.RequirementParseError: Parse error at "'sys_plat'": Expected stringEnd
Inside the bundle created by poetry I have:
$ grep pyvcam vega-0.1.0/PKG-INFO
Requires-Dist: pyvcam @ blob/pyvcam-2.1.0-cp39-cp39-linux_x86_64.whl; sys_platform == "linux"
According to the #2802 (linked above) I think there is meant to be a space prior to the ";". I have checked that the output of poetry build produces the same PKG-INFO entries.
I am about to submit a PR; I'm opening this issue for the context for that PR.
