Python-Extension: Debugger not running with Python 2.7

[dpalmetzvbg]

When trying to make a python-program with VSCode (Python 2.7.14) and run the debugger, an exception occurse. The program is very small:

Everything works perfectly well with python-3 environments.

import os
pass

Running without debugger is possible.

Environment data

• VS Code version: 1.43.0
• Extension version (available under the Extensions sidebar): Python-Extension 2020.2.64397
• OS and version: Windows 10 64 Bit (German)
• Python version (& distribution if applicable, e.g. Anaconda): 2.7.14 (shipps with ArcGis)
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): N/A
• Relevant/affected Python packages and their versions: none
• Relevant/affected Python-related VS Code extensions and their versions: Python-Extension
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info How to update the language server to the latest stable version vscode-python#3977): XXX
• Value of the python.languageServer setting: XXX

Expected behaviour

The debugger should start.

Actual behaviour

Exception is thrown.

Steps to reproduce:

Create a pyhton-file, save it and start the debugger.

Can you try with the new debugger? Instructions here on how to turn it on.

I followed the install-instructions, but it seems that the experimental debugger is not used, I do not get these messages mentioned in the link you sent me.

@dpalmetzvbg Check these settings, they should both be checked:
#2104 (comment)

If that do not fix then check the extension folder to see if multiple version of python extension are installed?
If so, then delete them all and follow instructions again #2104

If that does not work, please share your settings.json (redact any personal information)

I reinstalled the python extension, and there is only one extension, and also reinstalled the experimental extension, but it still does not work.

Now the experimental debugger is running, had to enable the telmetry-setting (the world belongs to those who read ‘till the end).

You're hitting microsoft/debugpy#69 now. We already have a fix, but until it gets into a new release, the workaround is to not use paths with non-ASCII characters on Python 2.7.

[dpalmetzvbg]

Yes, seems to be the same problem. Waiting for the fix. Von: Pavel Minaev <notifications@github.com> Gesendet: Dienstag, 17.
