Question

希望一切顺利。我是第一次通过Node.js设置量角器。这是AngularJS网站“运行E2E测试”下的教程的一部分： https://docs.angularjs.org/tutorial

但是，在通过提供的命令“npm run protractor”执行量角器时，我在Node.js命令提示符下出现以下错误：

E/launcher - Process exited with error code 199

npm ERR! Windows_NT 10.0.14393

以下是package.json文件中的内容：

  }
}

我不知道是否有其他人尝试过同样的教程并且遇到同样的问题？非常感谢任何帮助，谢谢。

因此，Protractor可以通过多种方式启动，最常见的方式是directConnect或seleniumAddress。由于e2e-tests/protractor.config.js文件中未设置任何值，因此假定值为directConnect。要让directConnect使用Chrome浏览器，您需要获得最新的chromedriver。要安装chromedriver：

./node_modules/.bin/webdriver-manager update --standalone=false --gecko=false

或者github angular-seed page中的建议另外还会下载selenium独立jar文件和gecko驱动程序（用于firefox）：

npm update-webdriver

无法从Node.js命令提示符运行量角器
