无法从Node.js命令提示符运行量angular器
希望一切安好。 我第一次通过Node.js设置量angular器。 这是在“运行E2Etesting”下的AngularJS网站上作为教程的一部分提供的： https ： //docs.angularjs.org/tutorial
但是，通过提供的命令“npm run protractor”执行量angular器时，Node.js命令提示符中出现以下错误：
E/launcher - Process exited with error code 199 npm ERR! Windows_NT 10.0.14393 npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "run" "protractor" npm ERR! node v6.9.1 npm ERR! npm v3.10.8 npm ERR! code ELIFECYCLE npm ERR! angular-phonecat@0.0.0 protractor: `protractor e2e-tests/protractor.conf.js` npm ERR!

Or if that isn't available, you can get their info via: npm ERR! npm owner ls angular-phonecat npm ERR! There is likely additional logging output above. 这是package.json文件中的内容：

我不知道是否有其他人也尝试过这个教程，并得到同样的问题？ 任何帮助将不胜感激，谢谢。
所以量angular器可以通过几种方式启动，最常见的是通过directConnect或seleniumAddress 。 由于在e2e-tests/protractor.config.js文件中没有设置值，所以假设的值是directConnect 。 要使directConnect与Chrome浏览器一起工作，您需要获得最新的chromedriver。 只需安装chromedriver：
./node_modules/.bin/webdriver-manager update --standalone=false --gecko=false
或者，在githubangular度种子页面 ，这将下载，另外，selenium独立的jar文件和壁虎驱动程序（这是用于Firefox）build议：
npm update-webdriver
