poetry add does not support paths without a directory component

[tyteen4a03]

• Poetry version: 1.2.2
• Python version: 3.8.10
• OS version and name: Windows 10
• pyproject.toml: N/A

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

poetry add my-wheel.whl results in the following error, however the same command poetry add ./my-wheel.whl works fine:

I've got the same problem. Changing the folder of the whl files seems to work.

[will-tha-mise]

I've got a similar seeming issue with a fresh install of poetry on a new machine when i run poetry install (regardless of the in_project config setting) I am seeing:

       Maybe not related, I am somewhat new to poetry

Getting the same error on Windows. @will-tha-mise did you find a work around for this?

Getting the same error on Windows. @will-tha-mise did you find a work around for this?

I ended up uninstalling and reinstalling python (and poetry) and it worked ok, suspect something was odd with my python install before

[rlleshi]

@will-tha-mise had u installed that python using pyenv?

[will-tha-mise]

@will-tha-mise had u installed that python using pyenv?

I'm not sure sorry, it was a work laptop with python pre-installed and unsure how they did it.
