Node.js fundamentals: how to upgrade the Node.js version

Node.js is being actively developed, and the latest stable version frequently changes. From time to time you will find a module that doesn’t work with your current version of Node and says that you need to upgrade.

Fortunately there is a very easy way of managing your node version, using the Node binary manager module ‘n’.

1: Check your current version of Node.

$node -v v0.6.12

2: Clear your npm cache

sudo npm cache clean -f

3: Install ‘n’

sudo npm install -g n

4: Upgrade to a later version (this step can take a while) You can specify a particular version like so:

sudo n 0.8.11

Or you can just tell the manager to install the latest stable version like so:

sudo n stable

5: Check the running version of Node to verify that it has worked:

$node -v v0.8.11

If the version doesn’t number output in step 5 isn’t what you were expecting, you may need to reboot.
