If you import platformdirs on python < 3.8, it now fails with release 2.6.1 unless you have the typing-extensions package already installed.
I think the issue is this change in release 2.6.1: https://github.com/platformdirs/platformdirs/compare/2.6.0...2.6.1#diff-e6813e0402941ad4943c8261f1ecfe5e1f9ccd55cb009b996fd785f3637fc7c2
I would suggest it should be:
```
from typing import TYPE_CHECKING
if TYPE_CHECKING:
if sys.version_info >= (3, 8): # pragma: no cover (py38+)
from typing import Literal
else: # pragma: no cover (py38+)
from typing_extensions import Literal
```
Alternatively, typing_extensions should be added as a dependency04 / LABELS
