Angular 4 CLI找不到名字'jasmine'

Question

我正在使用Angular 4 CLI(v.1.0.0)并处理测试我创建了一些使用jasmine来创建间谍的模拟.在IDE中一切看起来都没问题,但是在我收到的终端和错误中写着"找不到名字'茉莉花'".

起初我认为问题是茉莉没有添加到打字中,但我可以看到package.json包含茉莉花类型def的导入,所以我不确定缺少什么.

mocks.ts

export class MockAuthService {
  public login: Function = jasmine.createSpy('login');
}

export class MockHttpService {
  public delete: Function = jasmine.createSpy('delete');
  public get: Function = jasmine.createSpy('get');
  public post: Function = jasmine.createSpy('post');
  public put: Function = jasmine.createSpy('put');
}

运行ng服务在终端中返回以下错误消息.

C中的错误:/Users/efarley/Desktop/repos/prod/src/app/mocks/mocks.ts(2,23):找不到名字'jasmine'.C:/Users/efarley/Desktop/repos/prod/src/app/mocks/mocks.ts(6,24):找不到名字'jasmine'.C:/Users/efarley/Desktop/repos/prod/src/app/mocks/mocks.ts(7,21):找不到名字'jasmine'.C:/Users/efarley/Desktop/repos/prod/src/app/mocks/mocks.ts(8,22):找不到名字'jasmine'.C:/Users/efarley/Desktop/repos/prod/src/app/mocks/mocks.ts(9,21):找不到名字'jasmine'.webpack:编译失败.

您收到错误是因为TypeScript试图在app构建中包含模拟,而应用程序(正确地)不知道Jasmine.

通过将模拟添加到exclude数组中,从应用程序编译中排除模拟tsconfig.app.json:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2015",
    "baseUrl": "",
    "types": []
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts",
    "**/*.mock.ts"
  ]
}
