i'm using Mac.
All are lastest versions.
installed node with 'brew install node'
installed less with 'npm install less -g'
added *.less file in WebStorm 6.
added almost default settings for less except 'Program: /usr/local/bin/lessc'
oops, error, lessc not found,
fixed path to '/usr/local/share/npm/bin/lessc'
*.less files automatically saved, but no *.css.
tried this, tried that, no difference, nothing happens.
Oh, It works.
