InvalidRequirement error while installing using pipx

[29axe]

Confirmation

• I have read the README.md on the project homepage
• I have checked if identical issue already exists
• I have tried downgrading to find version that can be used as a workaround

The problem

I can't install PlexTraktSync using pipx on Win 10.
Tried downgrading versions up to 0.23.14.
Tried python 3.11 and 3.10.
I can't find where this furo requirements come from.

I'm guessing https://pypi.org/project/furo/ is installed with pip as system package, what does your pip list say?

you probably should report this to pipx:

• https://github.com/pypa/pipx

[29axe]

pip list says I have furo 2022.12.7.
But I can install other pipx packages. This error message seems to raise only when trying to install PlexTraktSync.

[glensc]

uninstall furo from pip, what then?

[glensc]

Anyway, it's not PlexTraktSync can do anything, so I'm closing it. Feel free to re-open if you found something that from PlexTraktSync we can do.

You can continue discussing if you found something or reported problem elsewhere.

[29axe]

uninstall furo from pip, what then?

Same thing happens.

Opened an issue on pipx.

EDIT: Just saw the suggested workaround in your pipx issue. Will test it later. Thx for raising the issue at pipx!

I have the same problem (see discussion #1268). Hope pipx Devs find a solution.
