启动你的开发服务器:

ng serve --live-reload false

此处的文档:https://github.com/angular/angular-cli/wiki/服务

如果这不起作用，请执行以下操作:

If that doesn't work then do:

ng serve --live-reload=false

您可以同时运行两个开发服务器，如下所示:

You could run two dev servers at same time as follows:

ng serve // with live reload on port 4200

ng serve --live-reload=false --port=4300 // without live reload on port 4300

这些可以同时运行.
