构建应用程序后Angular4不明异常

Question

我的应用程序使用 ng serve 运行良好，但是在使用 ng build --prod 构建它之后我得到了这个异常：

vendor.350ea18ab78ed7d28861.bundle.js:1 ERROR Error: No provider for e!
    at E (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at x (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at t._throwOrNull (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at t._getByKeyDefault (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at t._getByKey (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at t.get (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at Ue (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at t.get (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at Sn (vendor.350ea18ab78ed7d28861.bundle.js:1)
    at En (vendor.350ea18ab78ed7d28861.bundle.js:1)

问题是我找不到这个异常的来源，我不知道它是从哪里来的！

我正在使用 Angular 版本 4 和 ng CLI 版本 1.4.2，这是我的 package.json 文件：

"dependencies": {
    "@agm/core": "^1.0.0-beta.1",
    "@angular/animations": "^4.4.1",

    "ts-node": "~3.0.4",
    "tslint": "~5.3.2",
    "typescript": "~2.3.3"
  }

我该怎么办？
