Pylint not working

[PhilipMay]

Environment data

• VS Code version: 1.40.2
• Extension version (available under the Extensions sidebar): 2019.11.50794
• OS and version: MacOS and also Windows 7
• Python version (& distribution if applicable, e.g. Anaconda): conda python version 3.6.9
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Relevant/affected Python packages and their versions: pylint 2.4.4
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info How to update the language server to the latest stable version #3977): no

Expected behaviour

Since pylint is enabled it should find errors when I call "run linting" or save the .py file.

{
    "python.pythonPath": "/usr/local/miniconda3/envs/tf2/bin/python",
    "python.linting.pylintEnabled": true,
    "python.linting.enabled": true
}

Actual behaviour

It does not find anything when I save or call "run linting".

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

nothing here...

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

Thanks for the bug report! We just wanted to quickly acknowledge we received it and we will triage this as soon as we can.

@PhilipMay, in the "Python" output panel you should find the command that the extension is running to run pylint. What happens when you run that command manually at the terminal?

[PhilipMay]

Hi @ericsnowcurrently this here is the output when I run it from terminal:

It seems like pylint is called with wrong parameters.
