Steps to Upgrade Node.Js

Use the following steps to install or upgrade node.js to latest available version. Current NodeJs Version – First check current nodejs version on your system using following command. In my case it is

v0.10.37.rahul@tecadmin:~$ node -v
v0.10.37

Clean Cache Forcefully – Now clean all npm cache from your system forcefully.

rahul@tecadmin:~$ sudo npm cache clean -f

npm WARN using –force I sure hope you know what you are doing.

Install n Module – After cleaning all cache from your system, now install n modules using npm command.

rahul@tecadmin:~$ sudo npm install -g n

/usr/local/bin/n -> /usr/local/lib/node_modules/n/bin/n
n@2.0.2 /usr/local/lib/node_modules/n

Install Nodejs – Let’s install or update latest nodejs version on your system using n module.

rahul@tecadmin:~$ sudo n stable
install : node-v6.0.0
mkdir : /usr/local/n/versions/node/6.0.0
 fetch : https://nodejs.org/dist/v6.0.0/node-v6.0.0-linux-x64.tar.gz

Setup Binary Link – Now link your node binary with latest nodejs installed binary file using following command.

rahul@tecadmin:~$ sudo ln -sf /usr/local/n/versions/node/6.0.0/bin/node /usr/bin/node
