我有一个angular项目，当它在服务器上时工作正常，但在localHost上，它自动每30秒刷新一次浏览器
我没有写任何刷新页面的代码，比如像window.location.reload（）这样的代码
我测试了浏览器像Chrome，火狐，边缘和他们有同样的问题
我用commandPrompt运行项目，它仍然有问题
我还通过commandPrompt本身运行了vscode，它出现了问题，页面刷新
不知道是不是和浏览器缓存有关系，我也删了，可惜问题没有解决
最后，刷新时，控制台上会打印此错误，并重新加载页面

在我的Angular软件包版本中，它是这样的

我觉得我的问题是浏览器本身，因为我用localhost：4200运行了另一个项目，问题是一样的。
