Please tell me what is the problem with it.

Answer 1

Happened to me too... in recent distributions many packages install nodejs as the node.js executable, while spawn-sync attempts to call node, that is why this fails.

As a workaround, you can create a softlink from node to nodejs. Something like:

sudo ln -s which nodejs /usr/bin/node

Answer 2

Just install the latest version of nodejs and the error will get resolved.
Type the instructions in the terminal and node js will get updated:

1. $ sudo apt purge nodejs (for removing previous files of node js)
2. $ wget -qO- https://deb.nodesource.com/setup_7.x | sudo bash -(it will download latest version of node)
3. $ sudo apt-get install nodejs

and it is done.
