Commit 3817c89
Date 2018-03-09T13:53:26.466Z
Shell 1.7.9
Renderer 58.0.3029.110
Node 7.9.0

OS Linux 4.15.6-300.fc27.x86_64 #1 SMP Mon Feb 26 18:43:03 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Steps to Reproduce:

1. Prepared virtualfish, fishshell. docs
2. Changed the user setting:

    "python.venvPath": "$VIRTUALFISH_HOME",
    "python.envFile": "$VIRTUAL_ENV"

3. Select Python Interpreter.
4. Except base path: /usr/bin/python3/ and /usr/bin/python could not find virtualfish list envs.

This is more than a future request than actual issues.

Does this issue occur when all extensions are disabled?: Yes

If you would like to use environment variables in the settings, then please check the documentation

You'll need to change it as follows:

    "python.venvPath": "${env:VIRTUALFISH_HOME}",
    "python.envFile": "${env:VIRTUAL_ENV}"

Please let me know how this goes.

That would do the tricks, thank you for letting me know this. Sorry for the late reply though.
