未能从Node.js命令提示符运行量角器

希望一切都很好。我第一次通过Node.js设置量角器。这是“运行E2E测试”所规定的AngularJS网站上的教程的一部分： https://docs.angularjs.org/tutorial 未能从Node.js命令提示符运行量角器

然而，虽然通过提供的命令“故宫运行量角器”执行量角器，我得到的Node.js中的以下错误命令提示符：

E/launcher - Process exited with error code 199 

npm ERR! Windows_NT 10.0.14393

这里是关于的package.json文件中的内容：

    } 
}

我不知道是否有人尝试这样做同样的教程，并得到同样的问题？任何帮助将不胜感激，谢谢。

什么时候开始硒服务器？ –

你需要从你的package.json所在的文件夹运行'npm run protractor'命令。你也可以发布'package.json'文件的内容 –

我不确定我是否启动了硒服务器Danny，你能告诉我如何检查？当然，Sudharsen，我已经将package.json文件的内容添加到了问题中。 – AnderSco01

所以量角器可以有多种启动方式，最常见的是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。要使directConnect能够与Chrome浏览器一起使用，您需要获得最新的chromedriver。刚刚安装chromedriver：

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

或作为github angular-seed page建议将下载，另外，硒独立的jar文件和壁虎的驱动程序（用于Firefox浏览器）：

npm update-webdriver
