TypeError: providers [name] [0] is not a feature of Angular 4.0.1 npm test

Hi I'm new to Angular2, and when I try to run npm test with examples on the official angular.io site, I get this error:

providers[name][0] is not a function

I am using angular 4.0.1 and my package.json is as follows:

"dependencies": {

    "@angular/common": "^4.0.1",
    "@angular/compiler": "^4.0.1",

  },

      

        
        
        
      

    

I tried to do this but I couldn't find a clue. Has anyone faced the same problem?
