cannot format with black

Issue Type: Bug

Hi,

I cannot format with black anymore. It used to work, but now nothing happens when I run ‘Format Document’.

Looking at the output window, I get a message like:

> ~\Path\to\black --diff --quiet .\myfile.py
cwd: .

Nothing happens and it’s not clear if black runs at all. However running the exact same command in e.g. the Anaconda prompt, I do get the appropriate diff.

I’ve set the black path explicitly in the settings. If I don’t set it, it still doesn’t work but I get another error:

Formatting with black failed.
TypeError [ERR_INVALID_ARG_VALUE]: The argument 'file' cannot be empty. Received ''

My black is installed in a conda environment.

Please try the new Black formatter extension, and see if it helps in your scenario: https://marketplace.visualstudio.com/items?itemName=ms-python.black-formatter

Be sure to disable formatting with python extension: "python.formatting.provider": "none"
