无法运行服务 - 页面继续加载

Question

我正面临以下问题，我真的不知道是什么原因引起的。

请检查以下附件

当我尝试使用ng serve --open运行服务器时，服务器启动并编译所有内容。页面打开后，我立即收到一个空白窗口，似乎在等待某些东西。通过打开devtools，我注意到浏览器在很长一段时间内保持所选文件（超过1分钟，如图中所示）。如果我从浏览器中单击正在删除当前脚本的按钮，则表示所选文件已成功返回200代码，之后立即显示为101状态的websocker。我不知道哪一个悬挂，为什么但似乎他正试图切换一些协议。

如果我设法以足够快的速度打开浏览器的控制台，它会不停地打印此platform-browser.js:1770 Throttling history state changes to prevent the browser from hanging.之类的消息。

也许这会有所帮助
