installing Node.js

Whatever operating system you use, you'll need to install Node.js. We recommend doing this using nvm - the node version manager. Your machine should come with at least one of curl or wget. You can use either to install nvm:

curl version:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh | bash
