We (Shaka Player) have instructions in our docs on how to upgrade node and npm. I recommend you try this:

# Install an upgrade utility for node
sudo npm install -g n
# Upgrade node
sudo n stable
# Upgrade npm
sudo npm install -g npm

Wow those are hard to read.
You would be better off doing triple ` (backtick)

```sh
stuff
```

@logeshhy, you seem to have two versions of node installed: /usr/local/bin/node and /usr/bin/nodejs. This seems to be the root of your problem.

Try this (untested):

sudo mv /usr/local/bin/node /root/backup-node-v8
sudo npm install -g n
sudo n stable
sudo mv /usr/bin/nodejs /root/backup-nodejs-v4

After this, you should only have one copy of node, and it should be up-to-date. I hope.
