I have setup the file watcher in PhpStorm from it's default settings.
After modifying the filenames and adding --source-map
argument, the generated CSS file is empty.
Arguments:
--no-color
--clean-css
--source--map=$FileNameWithoutExtension$.min.css.map'
'$FileName$ $FileNameWithoutExtension$.min.css
And when I run the command directly in Mac Terminal, the file is generated well.
Uncheck Create output file from stdout
in Advanced Options
of your File Watcher
