Debugging Python File with Conda Environment Results in Permission Denied

[rm3028]

Hi,

When I try to debug a Python file using the Conda environment detected by the VS Code Python extension, it seems to use an incorrect configuration. The console shows the following automatically generated command and results in a Permission denied error:

/usr/bin/env /home/jovyan/.conda/envs/py310 /home/jovyan/.vscode-server/extensions/ms-python.debugpy-2025.10.0-linux-x64/bundled/libs/debugpy/adapter/../../debugpy/launcher 40869 -- /home/jovyan/test.py
/usr/bin/env: ‘/home/jovyan/.conda/envs/py310’: Permission denied

It appears that the extension tries to run the environment path itself as a command, which fails because it is a directory, not an executable.

The correct behavior should be to execute the Python binary like this:

/usr/bin/env /home/jovyan/.conda/envs/py310/bin/python ...

Could you please help me fix or work around this issue?

Thanks!

I too ran into this issue and just spent most of a day tracking down what broke my debugging environment which was working.

Work around for me is to un-install the python–environments extension

No need to uninstall, but just add this to your settings.json file

"python.useEnvironmentsExtensions": false

We encounter this too but using poetry. It's not specific to Conda environment.
