After upgrading the VS code extension to v2024.12.0, the debugger fails to launch in my Python 3.7 environment.

The following relevant extensions are installed in my virtual env, but I don't think they matter, as seems to be loading it from the global environment.

typing==3.7.4
typing-extensions==3.7.4

The error I get is:

...
File "/Users/vasan.subramanian/.vscode/extensions/ms-python.debugpy-2024.12.0-darwin-arm64/bundled/libs/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_plugin_utils.py", line 4, in <module>
    from typing import Tuple, Literal
ImportError: cannot import name 'Literal' from 'typing' (/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/typing.py

I had to revert to debugpy v2024.10.0 to be able to debug my programs.

@vasan-agrostar Python 3.7 has been deprecated for over a year. If you have to use python 3.7 you can pin the extension to an older version, see here for a compatibility: https://github.com/microsoft/vscode-python-debugger?tab=readme-ov-file#limited-support-for-deprecated-python-versions

But the extension says version 3.7 is supported:

Can we at least update the documentation if it is really deprecated? Also, when trying to run using python 3.6, it shows a message saying 3.6 is not supported. If 3.7 is not supported either, can we have a similar message? Getting an exception is very confusing.

Note for people who are trying to debug Python 3.7.x, the minimum version of Python Debugger extension that works isv24.10.0.
