No definitions found ever

Issue Type: Bug

To reproduce:

1. Create a file with the following contents:

    foo = 'foo'
    print(foo)
   

2. Focus foo in the second line

3. Press F12

Actual behaviour: VS Code prints “No definition found for ‘foo’” and does nothing else.

Expected behaviour: The focus should change to the start of line 1.

I’ve tested this both by opening a file and by creating a file in an existing workspace. I’ve tried on references to variables, functions, classes and methods. All of them fail, even when the definition is on the previous line and the extension even highlights the definition and focussed reference correctly.

Extension version: 2018.7.1 VS Code version: Code 1.26.0 (4e9361845dc28659923a300945f84731393e210d, 2018-08-13T16:25:59.521Z) OS version: Linux x64 4.17.14-arch1-1-ARCH Python version: CPython 3.6.5 Type of virtual environment used: Pipenv Relevant/affected Python packages and their versions: N/A

There was no VS Code output whatsoever while testing this. However, in the development console I get this message:

Python Extension: sendCommand jediProxy, Error (sendCommand) This socket is closed

Apparently this isn’t part of the Python extension by default. My bad.

"python.jediEnabled": true improves things ever so slightly, by finding definitions for variables (and only variables, it seems).

You’re right, this seems to be related to the interpreter. I’ll just close this issue in favour of the others. And for anyone with similar problems, set "python.jediEnabled": true and click “Later” every time you get the “IntelliCode Python support requires you to use the Microsoft Python Language Server (preview).” prompt.
