How do I update Node.js?

Answer 1

I had the same problem, when I saw that my Node.js installation is outdated.

These few lines will handle everything (for Ubuntu):

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

After this node -v will return you the latest available version.

Answer 2

If you have Homebrew installed (only for macOS):

$ brew upgrade node

Answer 3

As some of you already said, the easiest way is to update Node.js through the Node.js package manager, npm. If you are a Linux (Debian-based in my case) user I would suggest to add these lines to your .bashrc file (in home directory):

function nodejsupdate() {
    ARGC=$#
    version=latest
    if [ $ARGC != 0 ]; then
        version=$1
    fi
    sudo npm cache clean -f
    sudo npm install -g n
    sudo n $version
}

Restart your terminal after saving and write nodejsupdate to update to the latest version of Node.js or nodejsupdate v6.0.0 (for example) to update to a specific version of Node.js.

BONUS: Update npm (add these lines to .bashrc)

function npmupdate() {
    sudo npm i npm -g
}

After restarting the terminal write npmupdate to update your node package manager to the latest version.

Now you can update Node.js and npm through your terminal (easier).

On CentOS 7 you can do the following:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable
sudo ln -sf /usr/local/n/versions/node/5.4.1/bin/node /usr/bin/node
node –v (Should show updated version now)
npm rebuild node-sass (Optional: if you use this)

Note: The symlink is required to link your node binary with the latest Node.js installed binary file.

Answer 5

Some Linux distributions such as Arch Linux have Node.js in their package repositories. On such systems it is better to use a standard package update procedure, such as pacman -Suy or analogous apt-get or yum commands.

As of now (Nov 2016) EPEL7 offers a pretty recent version of Node.js (6.9.1 which is an up-to-date LTS version offered on the Node.js home page). So on CentOS 7 and derivatives you can just add EPEL repository by yum install epel-release and yum install nodejs.

CentOS 6/EPEL6 has 0.10.x which isn't supported upstream since Oct 2016.
