ImportError: cannot import name 'Any' from 'typing_extensions'

[dcambie]

Since #1831 textual uses typing_extensions.Any (e.g. in actions.py#L6).

Any was introduced in typing_extensions 4.4.0, (see changelog) however, the minimum version of typing_extensions required by textual in the pyproject.toml seems to be 4.0.0.

This creates the following error when textual is installed in a venv where typing_extensions is already present with version higher than 4.0 but lower than 4.4.

Traceback:

Fixed locally by pip install -U but asking for the obvious fix of bumping the dep. Congrats on the great library btw ;)

You are awesome for this bug report. You are correct, fixed by (in my case) poetry update (thank you) but I just ran into the same error.

[willmcgugan]

Thanks, will bump that in the next release.

FWIW:

$ poetry update

• Updating typing-extensions (4.3.0 -> 4.5.0)

python -m textual failed before but works after 👍

After a pip install -U typing, and a restart of the kernel, it was ok.
Thanx for the tip
