Issue Type: Bug

The jupyter extension sets the PYTHONPATH variable incorrectly when a .env file contains relative path definitions.

To reproduce:

  • On Windows 10
  • vscode project base in C:\Users\My User\Documents\vscode_test_project
  • .env file in above direcory with the content PYTHONPATH=./some-library
  • python file subdir\test.py in above directory that is empty except for the line # %% opened in editor
  • Click on "Run Cell"
  • Jupyter opens
  • in jupyter notebook execute import sys; sys.path

Expected result:

['c:\\Users\\My User\\.vscode\\extensions\\ms-toolsai.jupyter-2021.2.603412351\\pythonFiles\\.does-not-exist',
 'C:\\Users\\My User\\Documents\\vscode_test_project\\some-library',
 'c:\\Users\\My User\\.vscode\\extensions\\ms-toolsai.jupyter-2021.2.603412351\\pythonFiles',

 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\DLLs',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env',
 '',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages',

 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages\\IPython\\extensions',
 'C:\\Users\\My User\\.ipython']

Actual result:

['c:\\Users\\My User\\.vscode\\extensions\\ms-toolsai.jupyter-2021.2.603412351\\pythonFiles\\.does-not-exist',
 'C:\\Program Files\\Microsoft VS Code\\some-library',

 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\DLLs',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env',
 '',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages\\win32',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages\\win32\\lib',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages\\Pythonwin',
 'C:\\ProgramData\\Miniconda3\\envs\\vscode_test_env\\lib\\site-packages\\IPython\\extensions',
 'C:\\Users\\My User\\.ipython']

Note the invalid value of the second line containing the path for some-library. This should always be relative to the location of the location of the .env file.

Also of concern to me seems to be the first line that seems to contain part of an error message with .does-not-exist.

One observation that might help with debugging this issue:

Playing with the .env file I discovered that the problem can be partially fixed by setting a worspaceFolder environment variable in the .env file manually. That fixes the first line containing the remnant of an error message, the second line is however still expanded relative to the python file used to start the notebook rather than relative to the .env file.

Content of .env:

workspaceFolder=C:\Users\My User\Documents\vscode_test_project
PYTHONPATH=./some-library

Output of import sys; sys.path:

['c:\\Users\\My User\\Documents\\vscode_test_project',
 'c:\\Users\\My User\\Documents\\vscode_test_project\\subdir',
 'c:\\Users\\My User\\Documents\\vscode_test_project\\subdir\\some-library',

I'm looking at this right now (though I am on Mac and not windows) and I don't see the same issue that you are seeing:

Let me poke around a bit more here quick.

Do I have your file layout correct? I also tried this with the subdir and that is also working.

vscode_test_project (.env file in here)
vscode_test_project/subdir (python file with cell marker here)

@IanMatthewHuff Thanks for looking into this. Yes your directory structure is correct. See my attached screenshots.

You seem to be using linux for reproducing this. I think this might be a windows-specific problem. My second post indicates that there are problems with variable substitution on windows. I.e. why else would adding a workspaceFolder environment variable affect the paths.

Please let me know if there is anything I can do to help you debug this.

Alternative 1: simple .env file

Another thought: could part of the issue be that my project path contains a space?

Just realized I can test this myself of course. I move the vscode_test_project directory to the root of an external harddrive. This got rid of the space in the project path. - No improvement at all from what I can see.

@secure-mail-documentation-project Sorry about this being hard to work through, without having the issue on my box it's a bit hard to debug.

This isn't a full fix but as a possible workaround, we have a setting to specifically run python commands at the start of any notebook or interactive window session. If you have python code to manually add something into sys.path you could put it in here and that should run that code for any interactive sessions that you start. The setting is Jupyter: Run Startup Commands.

Currently I'm looking at all the info on configuring .env files here:
https://code.visualstudio.com/docs/python/environments#_environment-variable-definitions-file

One thing to try. With just the PYTHONPATH specified instead of printing out sys.path could you instead import os and print os.environ? I'd like to see what the PYTHONPATH looks like there before it gets added to the sys.path.

No problem. I have some self-interest that this get's fixed. I am happy to help debug it.

@IanMatthewHuff Looking at the PYTHONPATH environment variable I noticed my path separator was different from the others: / instead of \. I changed it to the windows standard but that made no difference.

I did notice a curious effect however to do with changing the .env file in a running vscode session:

  1. Start vscode with .env containing: PYTHONPATH=./some-library
  2. Start interactive window
  3. sys.path is mangled
  4. Close interactive window
  5. Start interactive window again
  6. sys.path is still mangled

If one however modifies .env during a running vscode session, paths are almost correct:

  1. Start vscode with .env containing: PYTHONPATH=./some-library
  2. Start interactive window
  3. sys.path is mangled
  4. Close interactive window
  5. Change .env to read PYTHONPATH=.\some-library
  6. Start interactive window again
  7. sys.path now are almost correct:

Output of sys.path:

Further observations:

  • After changing .env once one can change it back to its original content and sys.path remains OK.
  • It does not matter how one changes .env at all. What matters is only that .env gets changed once duing a running vscode session.

It would appear that the .env-file watcher is running some crucial action when the file is changed that does not get run at a normal jupyter startup. In fact, the PYTHONPATH environment variable has less content after .env was changed once than if it was never changed...

On a sour note: the question of what relative PYTHONPATH definitions resolve to is unaffected by this. They are still relative to the directory of the file from which the interactive window was started rather than relative to the location of the .env-file.

@greazer I just saw, that you added 'info-needed'. Could you please explain what you need to proceed? As far as I am aware, I have provided all info requested by @IanMatthewHuff. Did I misunderstand something? I am more than happy to help debugging this.

In my case, the .env file doesn't load at all for a .env file as simple as,

TEST_VAR=123456

then check with,

import os
print(os.getenv("TEST_VAR"))

I've managed to identify the cause of the issue, when using non-conda issues we dont use the env variables at all.
