Issue

trying to poetry add a wheel hosted on GitHub fails with [ValueError] Could not parse version constraint. Specifically, this wheel: https://github.com/gotenna/PublicSDK/raw/master/python-public-sdk/goTenna-0.12.5-py3-none-any.whl

I also tried downloading the wheel and installing from local disk, with same error.

Try running poetry add -vvv ... to get traceback information

Hello @src-r-r ,

this issue is talking about version parsing problems during installing a wheel and not a plain project from git.

The original issue seems to be fixed in the current release. So I will close it.

In your case the problem is, that poetry needs to parse the setup.py. There the version is loaded dynamically from another resource. Because poetry doesn’t run the setup.py it is unable to get the version.
