Please provide your Pipfile.

If you specified somepackage; python_version in "3.4, 3.5, 3.6"' as a marker, that's not a valid marker and will continue to throw this error

Thank you.

I am experiencing the same issue. Nothing in my project has changed -- the error is only introduced with pipenv v11.1.4. Reverting to v11.1.3 or earlier solves it for me.

@notdaniel please provide your Pipfile. We can't fix the bug if we can't reproduce it :)

Thank you. I'll work on a fix ASAP. It's been a long day, though — so might not be until tomorrow.

This should be fixed in #1624 -- feel free to try it out and let me know: pip install -e git+https://github.com/pypa/pipenv.git@bugfix/resolver-markers#egg=pipenv

@msheiny How does that issue help? I didn't get it.

[techalchemy]
