Could not find 'black'. The program may not be installed.

[Doekeb]

Description

Atom Beautify cannot find Black. Running Atom Beautify on even an empty Python file fails with the following message:

Could not find 'black'. The program may not be installed.

See black installation instructions at https://github.com/Glavin001/atom-beautify#beautifiers or go to https://github.com/ambv/black#installation
You can configure Atom Beautify with the absolute path to 'black' by setting 'Executable - black - Path' in the Atom Beautify package settings.
Your program is properly installed if running 'which black' in your Terminal returns an absolute path to the executable.

Steps to Reproduce

1. Create an empty Python file, e.g. test.py.
2. Run command Atom Beautify: Beautify Editor
3. The above error message is returned

Note: I have double-checked that black is installed (in my system python—not a virtual environment). Running which black returns the absolute path. I get the same results as above even if I set the absolute path of the executable in Atom Beautify settings. Additionally, I can successfully run black on a file manually from the command line.

I am experiencing the same issue and have followed the same troubleshooting steps described by Doekeb without success :/

possible insight that might help debugging:

mine was working fine then i did an pip3 install --upgrade black New version (broken):

❯ black --version
black, 21.12b0 (compiled: no)

I cant remember what version I had before but I rolled back to pip3 install black==21.10b0 and its working again

[ThatXliner]

Same. Only black==21.10b worked

[claytonjroberts]

For anyone looking for a quick solution: pip install --upgrade black==21.10b0

[jeanfrancoiscaty]

Figured out the issue, version number is getting reported differently now. regex is looking for black, version X.Y.Z but version is now black, X.Y.Z

Cracked open packages/atom-beautify/src/beautifiers/black.coffee and updated the catch:

          try
            text.match(/black, version (\d+\.\d+)/)[1] + "." + text.match(/b(\d+)$/)[1]
          catch
            try
              text.match(/black, version (\d+\.\d+)/)[1] + ".0"
            catch
              text.match(/black, (\d+\.\d+\.\d+)/)[1]

Good enough for me, will look into contributing a proper PR for it when I have the bandwidth.
