Install Node.js on Ubuntu

Using the apt package manager

sudo apt-get update    
sudo apt-get install nodejs
sudo apt-get install npm
sudo ln -s /usr/bin/nodejs /usr/bin/node

# the node & npm versions in apt are outdated. This is how you can update them:
sudo npm install -g npm
sudo npm install -g n
sudo n stable # (or lts, or a specific version)

Using the latest of specific version (e.g. LTS 6.x) directly from nodesource

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
apt-get install -y nodejs

Also, for the right way to install global npm modules, set the personal directory for them (eliminates the need for sudo and avoids EACCES errors):

mkdir ~/.npm-global
echo "export PATH=~/.npm-global/bin:$PATH" >> ~/.profile
source ~/.profile
npm config set prefix '~/.npm-global'
