推荐答案

Go to you package.json and change all @angular dependencies to 4.0.0 or any version you want.  
Then do the same for @angular-cli with the version number you want it to be. just like the code below

- Save that file    
- Delete you node-modules folder  
- run `npm install` or `yarn` if you are using yarn. 




 {
    "name":"crud-operation",
     "version":"0.0.0",
     "license":"MIT",
     "scripts":{
     "ng":"ng",
          "start":"ng serve",
          "build":"ng build --prod",
          "test":"ng test",
          "lint":"ng lint",
          "e2e":"ng e2e"
       },
       "private":true,
       "dependencies":{
          "@angular/animations":"4.0.0",
