Issue

I'm not sure if this is a poetry bug or a tox bug, but I figured I'd start here. The issue seems to be with how:

Requires-Dist: filelock (>=3.9.0,<4.0.0) ; extra == "extras1" or extra == "extras2"

in the PKG-INFO

Then when tox is run with e.g., extras = extras1, you get:

py-extras1: install_package_deps> python -I -m pip install 'filelock<4.0.0,>=3.9.0; or extra == "extras2"'
...
pip._vendor.packaging.markers.InvalidMarker: Invalid marker: 'or extra == "extras2"', parse error at 'or extra'

Environment

Provide at least:

• OS: macos
• pip list of the host Python where tox is installed:

./.venv/bin/pip list
Package       Version
------------- -------
cachetools    5.2.0
chardet       5.1.0
colorama      0.4.6
distlib       0.3.6
filelock      3.9.0
packaging     22.0
pip           22.3.1
platformdirs  2.6.2
pluggy        1.0.0
pyproject_api 1.2.1
setuptools    65.5.0
tox           4.1.0
virtualenv    20.17.1
