NodeJS installation

NodeJS is required for various components of MountainLab. If you are on Ubuntu, you can do the following prior to MountainLab compilation:

sudo apt-get install nodejs npm

Otherwise, visit the NodeJS home page

Note: depending on how nodejs is named on your system, you may need to do the following (or something like it):

sudo  ln -s /usr/bin/node /usr/bin/nodejs
