我正在尝试用 typescript 编写 Protractor + cucumber 组合。我的项目有一个简单的功能，可以打开页面并输入三个字段。我无法运行 Protractor 。它让我低于错误。

我已经使用 Angular-cli ( https://github.com/angular/angular-cli ) 制作了我的项目，我尝试遵循 https://github.com/samvloeberghs/protractor-gherkin-cucumberjs-angular2 .

我需要做一些额外的步骤让 Protractor 首先编译 typescript 文件吗？还是我遗漏了什么？

最佳答案

主要问题是:

Cannot find namespace 'protractor'

你需要解决这个问题。您需要全局定义 protractor 类型或

import {protractor} from 'protractor'

我不知道你的 tsconfig.js 或 system.config.js 但你基本上必须启用上面的 tsc解析 protractor 模块。

关于javascript - Protractor + cucumber + typescript 失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38542681/
