问题

I was using SASS as CSS pre-processor for Drupal theme. Where in the command line if I use $ compass watch. It keep on watching the change in .scss file and apply to .css file.

Just I am trying Bootstrap theme and there I am using LESS CSS pre-processor, Where I have to use $ lessc less/style.less css/style.css every time to apply change.

What is the equivalent of $ compass watch for LESS.

1. You need to install less-watch-compiler:
   npm install -g less-watch-compiler

2. Make sure you installed less globally:
   npm install -g less

3. In Terminal, navigate to your working directory path and run the following command:
   less-watch-compiler FOLDER_TO_WATCH FOLDER_TO_OUTPUT
