问题
I've recently installed less in Ubuntu 14.04 but it doesn't work at all.
I've installed npm and node via
sudo apt-get install node npm
and then I've installed less with
npm -g install less
Problem is that every time I try to run
lessc bootstrap.less > theme.css
the output is an empty css file.

I've found a solution to this problem.
I wrongly installed the node package instead of nodejs.
After removing node and installing nodejs I got this error
/usr/bin/env: node: No such file or directory
I just executed
sudo ln -s /usr/bin/nodejs /usr/local/bin/node
More info can be found here: Express.js: No Such file or directory
