TypeError：providers [name] [0]不是Angular 4.0.1 npm test函数

嗨,我是Angular2的新手,当我尝试使用onicial angular.io网站上的示例运行npm测试时,我收到此错误：

providers[name][0] is not a function
TypeError: providers[name][0] is not a function

我正在使用angular 4.0.1,我的package.json是下一个：

"dependencies": {
    "@angular/animations": "^4.0.1","@angular/common": "^4.0.1","@angular/compiler": "^4.0.1","@angular/compiler-cli": "^4.0.1","@angular/core": "^4.0.1","@angular/forms": "^4.0.1","@angular/http": "^4.0.1","@angular/material": "^2.0.0-beta.2","@angular/platform-browser": "^4.0.1","@angular/platform-browser-dynamic": "^4.0.1","@angular/platform-server": "^4.0.1","@angular/router": "^4.0.1","@ng-bootstrap/ng-bootstrap": "^1.0.0-alpha.22","@types/d3": "^4.5.0","@types/jasmine": "^2.5.47","@types/lodash": "^4.14.50","@types/node": "^6.0.68","bootstrap": "^4.0.0-alpha.6",...
    "jasmine-spec-reporter": "^2.7.0","jquery": "^3.1.1",...
    "karma": "^1.5.0","karma-jasmine": "^1.1.0","karma-remap-istanbul": "^0.2.2","lodash": "^4.17.4",....
    "typescript": "^2.2.2","zone.js": "^0.8.4"
  },

我试图谷歌它,但我没有找到线索.有人遇到过同样的问题吗？
