Node.js Installing Node.js Install Node.js on Ubuntu
Example
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# the node & npm versions in apt are outdated.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'
