   The fix for this is already merged — it just hasn't been released.

   #2 added the parentheses and was merged on 2026-02-09, and main currently has:

   except (json.JSONDecodeError, TypeError):

   But talk-python-cli 0.2.0 was uploaded to PyPI on 2026-02-07, one day before that PR was opened. Since there's been no release since, uv tool install talk-python-cli still pulls the pre-fix build — which is why installing from the repo works while installing from PyPI doesn't.

   Root cause, for anyone hitting this: unparenthesized except A, B: only became valid syntax in Python 3.14 (PEP 758). The package metadata declares Requires-Python >=3.12, so on 3.12 and 3.13 it's a hard SyntaxError at import — the released artifact is broken across most of its own supported range.

   Two workarounds until a release goes out:

   uv tool install "git+http://github.com/talkpython/talk-python-cli"   # has the fix
   uv tool install --python 3.14 talk-python-cli                        # dodges the syntax error

   A 0.2.1 release should close this out. Thanks for the CLI — working nicely here otherwise.
