And when i install importlib-metadata in my Virtual environment,The error messages disappear.But in my usage, importlib-metadata is unnecessary.

It is a logging error, hence why it's not critical and doesn't affect the actual debugging experience. Still a bug, though; thank you for reporting!

[cctv130]

This bug also exists on windows, when will it be fixed? @int19h

I'm really curious as to which package is actually triggering it, because name is not supposed to be optional.

As a workaround, you can edit the file in which it reports the error (.../debugpy/common/log.py) and replace the offending line:

report("    {0}=={1}\n", pkg.name, pkg.version)

with pass.

the same issue on MacOS with conda. all vscode plugins are updated.

I've also been experiencing this bug in the last month. I am on the latest VS Code 1.86.2 on Ubuntu 20.04.

Hi. I am facing the same error on Python 3.9 on macOS.

This error is not about a package missing the name, it is the fact that the offending code is calling into a python module importlib.metadata which is missing the attribute name. That is because the name attribute on Distribution class is only introduced in Python 3.10, but does not exist in Python 3.9. In other words, the author of the offending code installed the latest Python and assumed everyone is on the latest Python, and the CI was set up to assume the same. But unfortunately, in the real world everyone uses different versions of Python. Even if a user has a latest version installed, they can still be installing a different version in a virtual environment for a specific project. And if the user has Python 3.8 or 3.9, the attribute will always be missing from this module, regardless of which package is installed.

I think this is a regression, and the best fix is to check whether this attribute is available from the Python built-in module, and log it optionally if it is available. Additionally, it would be nice for CI to test against supported versions of Python and not just the latest version.

Thanks.

I have the same issue i can working but is a horrible message

[tim-jones]

I installed the missing package importlib-metadata and this error went away. vscode 1.85.1

I installed the missing package importlib-metadata and this error went away. vscode 1.85.1

Thanks for the solution. It works for me.
