我安装了npm install protractor -g，然后尝试更新
使用命令“ webdriver-manager更新”的webdriver-manager，它发生：

如果我尝试使用“ webdriver-manager start”命令启动webdriver-manager，它会显示“ Selenium Standalone不存在。请使用webdriver-manager update --standalone安装”

我不知道该怎么办，您能帮我吗？
最佳答案
WebDriver Manager在update上下载基本驱动程序。不确定您是从Docker容器，无所事事的VM还是在VPN内运行它。
它是从以下来源下载的，并且屏幕快照中的ipaddress表示您在连接https://github.com/mozilla时遇到问题。在ping github上，我看到了相同的IP。
资料来源：来自webdriver-manager configs
"cdnUrls": {
"selenium": "https://selenium-release.storage.googleapis.com/",

"iedriver": "https://selenium-release.storage.googleapis.com/",
"androidsdk": "http://dl.google.com/android/"
}
您能否按如下所示ping命令查看是否能够从执行
webdriver-manager update的位置手动访问上述资源（Chrome＆seleniumServer＆Gecko）C:\Users\<<>>\WebstormProjects\demo>ping github.com
