- In the same directory where you have - package.jsoncreate a- npm-shrinkwrap.jsonfile with the following contents:- 1 
 2
 3
 4

 6
 7- { 
 "dependencies": {
 "graceful-fs": {
 "version": "4.2.2"
 }
 }
 }
- Run - npm install, and don’t worry, it’ll update- npm-shrinkwrap.jsonwith a bunch of content.
- Run - gulpto start the project.
