If you don’t want to use GUI to compile LESS on Windows, there is a clean way to get lessc command on Windows command line. It only requires you to install node.js, which is required by original lessc anyway.
So, install node.js (http://nodejs.org/) and install “less” module for node.js. The latter provides lessc executable (lessc.cmd on Windows) as well, so you should only make sure it gets under your PATH in Windows.
If you don’t have node.js yet, here are step-by-step instructions:
- Install node.js (http://nodejs.org/)
- In new command-line, go to node.js installation directory (where node.exe is located), and execute
> npm install less(make sure you do so from node.js installation directory only) - Latter downloads less module for node.js, as well as
lessc.cmdtonode_modules/.bin/directory. Add this directory to PATH - Now, in new command line you may enjoy the use of
lesscas usual
