KeyError: 'PATH' on import in interactive window

[janosh]

Trying

import xgboost

in the interactive window throws

KeyError: 'PATH'

but works fine in terminal.

As suggested by @bbcCorp in microsoft/vscode-python#436, I tried creating a .env file with

echo "PATH=\$PATH" >> .env

but the issue persists. I'm running the latest VS Code and insider's build of the Python extension.

Perhaps related: The "Select Interpreter" prompt isn't showing any of my conda envs, only the system Python.

I tried specifying

"python.condaPath": "/usr/local/Caskroom/miniconda/base/bin/conda",

as suggested by @DonJayamanne here. Didn't help though.

[DonJayamanne]

Thanks for reporting this issue.
Whats version of the extension are you using?

[janosh]

I'm running the latest VS Code and insider's build of the Python extension.

Python Ext Version: 2019.12.53195-dev

VS Code Version: 1.40.2

[DonJayamanne]

Unfortunately we introduced a bug in the insiders version of the extension that resulted in conda and virtual environments not being listed out.

Please could you download the following file manually and try it out.
https://dev.azure.com/ms/_apis/resources/Containers/3614481/VSIX?itemPath=VSIX%2Fms-python-insiders.vsix

[janosh]

Thanks for the suggestion. Like I said, I'm already running today's insider's build. I redownloaded and installed it again from here just now but the issue persists.

[DonJayamanne]

Yes, thanks, however the insiders is also broken.
Please could you install from the link I provided.

[janosh]

I'm only getting a white page with a JSON object when clicking your link.

{"$id":"1","innerException":null,"message":"TF400813: The user 'Windows Live ID\\janosh.riebesell@gmail.com' is not authorized to access this resource.","typeName":"Microsoft.TeamFoundation.Framework.Server.UnauthorizedRequestException, Microsoft.TeamFoundation.Framework.Server","typeKey":"UnauthorizedRequestException","errorCode":0,"eventId":3000}

So I uninstalled the insider's and installed the latest official release where everything is back to working. 👍

[DonJayamanne]

Apologies for that. The insiders build is back up, if you can please do download it from the link you had used earlier. (https://pvsc.blob.core.windows.net/extension-builds/ms-python-insiders.vsix)

[janosh]

Yep, insider's is showing conda environments again. 👍

The KeyError: 'PATH'  is still happening though (and only in insider's).

[DonJayamanne]

@janosh

• Please could you try this once again.
• Please could you try running a simple python cell as follows:

import os
print(os.getenv('PATH'))

Forgot to mention, I'm unable to replicate this at my end.

• Please could you provide the following info:

  • OS
  • Python version
  • Is it a conda environment?

• Are you using and .env file or similar with custom environment variables?

[janosh]

@DonJayamanne Just tested this again and all is back to working now with the insider's. Thanks a lot! 👍

[DonJayamanne]

@janosh thanks for testing the insiders and getting back.
