Hi Harpreet Singh,

I had the same problem. This error is caused by using an older version of Node. The Strip-bom module is now using ES2015 (ES6) syntax which requires Node 5.0+. (See Node's ES2015 support list here)

To test your version of Node, run:

node -v

If it's less than 5.0, you'll need to update it. You can download the newest version of Node here:


If the gulp command gives a "gulp: command not found" in your console. You should install gulp globally and it is fixed ;)

Hope this helps!
