量角器 + 黄瓜 + 打字稿失败

Question

• 节点版本：4.4.5
• 量角器版本：3.3.0
• 浏览器：chrome
• 操作系统和版本Win 7

我正在尝试在打字稿中编写量角器 + 黄瓜组合。我的项目有一个简单的功能是打开页面并输入三个字段。我无法运行量角器。它把我扔到了错误之下。

我使用 Angular-cli (https://github.com/angular/angular-cli) 制作了我的项目，并尝试关注 https://github.com/samvloeberghs/protractor-gherkin-cucumberjs-angular2。

我需要做一些额外的步骤让量角器首先编译打字稿文件吗？还是我缺少什么？

Answer 1

主要问题是这样的：

找不到命名空间“量角器”

你需要解决这个问题。您要么需要在全局范围内定义 protractor 类型，要么

import {protractor} from 'protractor'

我不知道您的tsconfig.js 或system.config.js，但您必须启用上述功能才能使tsc 解析protractor 模块。

Answer 2

将打字稿更新到 2.0+ 和量角器 4.0+ 。确保更新您的全局和本地版本。将 typescript 更新到 2.0 应该可以修复它。
