[BUG] ModuleNotFoundError when importing rich.markdown

[mcdonnnj]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

I ran into this issue in a dependent projects (ansible-lint), but I believe this bug was introduced in #2977 and pushed out with v13.4.0. A package dependency was incorrectly implemented which results in failure when this package is used with Markdown.

I see the following error in ansible-lint:

  File "/home/mcdonnnj/.pyenv/versions/python_testing/lib/python3.11/site-packages/ansiblelint/color.py", line 7, in <module>
    import rich.markdown
  File "/home/mcdonnnj/.pyenv/versions/python_testing/lib/python3.11/site-packages/rich/markdown.py", line 7, in <module>
    from typing_extensions import get_args
ModuleNotFoundError: No module named 'typing_extensions'

This is because

rich/rich/markdown.py

Line 7 in cf13882

from typing_extensions import get_args

does not import as is done elsewhere in this project such as

rich/rich/emoji.py

Lines 10 to 13 in cf13882

	if sys.version_info >= (3, 8):
	from typing import Literal
	else:
	from typing_extensions import Literal # pragma: no cover

and because typing_extensions is only installed if Python <3.8 per

rich/poetry.lock

Line 359 in cf13882

typing_extensions = {version = ">=3.7.4", markers = "python_version < \"3.8\""}

I could be mistaken but that seems to be the most likely cause of this failure.

Hey, I'm also hitting this issue when running ansible-lint. Glad to know it's not just me. 😅

Yeah it looks like a fix is already on the way per 1176f81.

[willmcgugan]

Please try v13.4.1

[aroberts87]

Works like a charm for me, @willmcgugan! Thanks!

[mcdonnnj]

@willmcgugan After updating I no longer see the failure when running ansible-lint, thanks for the fast turnaround!
