poetry: Inclusion of git dependency causes poetry to TypeError

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Debian bullseye/sid

• Poetry version: Poetry version 1.1.4

• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/hlieberman/3057f3b572355cc6699cc44bdf352979

Issue

It’s possible this is related to the now-closed issue #2027, but the solutions listed in that issue don’t appear to be applicable in this situation (there are no .egg-info files involved).

After adding a git repository dependency to my project, all poetry commands involving dependency resolution now fail with a TypeError expected string or bytes-like object from poetry.helpers.canonicalize_name.

poetry show, poetry install, and poetry update all cause these errors. The project is essentially barren; there’s no actual code put down yet, so it should be relatively simple to replicate.

Exception output:
