typescript - Typescript 2 茉莉花类型

Question

我正在使用 Typescript 2，除非我将 a/// <reference path="..." />放在我的规范文件的顶部，否则我会收到一个错误Cannot find name 'describe'

这是我的规格文件：

/// <reference path="../../../../node_modules/@types/jasmine/index.d.ts" />

import { DashboardSlotComponent } from './dashboard-slot.component';
import { DashboardSlot } from './dashboard-slot.model';

describe('Given a dashboard slot component', () => {
    let sut: DashboardSlotComponent;

    beforeEach(() => {
        sut = new DashboardSlotComponent();
    });
...

包.json

"typescript": "2.0.2",

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",

    ]
  },

  },

}

我正在使用带有 Typescript 2 扩展的 Visual Studio 2015。

Answer 1

使用 Typescript 2，尝试：

/// <reference types="jasmine" />

并确保你 npm install @types/jasmine
