ModuleNotFoundError: No module named 'typing_extensions'

tlsclient imports `typingextensions at load and it is not installed. Run python -m pip install typing_extensions` (or reinstall tls-client normally so pip resolves it). The import works right after.

The error

ModuleNotFoundError: No module named 'typing_extensions'

Fix it

1. Install typing_extensions

python -m pip install typing_extensions

Expected: Successfully installed typing_extensions-....

2. Confirm the chain

python -c "import tls_client; print('ok')"

Expected: prints ok.

3. If it recurs, reinstall tls-client with dependencies

python -m pip install --force-reinstall tls-client

Expected: pip restores the declared dependency set.

When this applies

• import tls_client fails naming typing_extensions
• the traceback shows tls_client's own modules importing it
• a --no-deps install or a minimal image

When it does NOT apply

• No module named 'tls_client' is the parent package missing

Compatibility

All tls-client 1.x/2.x declare typingextensions. typingextensions itself supports Python 3.8+.

Why it happens

typingextensions backports new typing features to older Pythons, and tlsclient uses them at import time. It is a declared dependency, so its absence means the install was done with --no-deps, a resolver glitch, or a hand-pruned requirements file.

Edge cases

• On Python 3.11+, much of typingextensions is redundant, but tlsclient still imports the package itself, so it must be present regardless.

In gh:h4ck3dr4du/crunchyroll-account-checker#5, importing tlsclient failed with ModuleNotFoundError: No module named 'typingextensions' through the tlsclient import chain, and installing typingextensions resolved it. Source: https://github.com/h4ck3dr4du/crunchyroll-account-checker/issues/5
