我正在通过angular-cli版本1.0.0-beta.28.3创建angular 2应用程序。

I am creating angular 2 application through "angular-cli" version "1.0.0-beta.28.3".

当我使用命令npm start时或ng serve，该应用程序的工作价格为 http：// localhost：4200

When I am using commands "npm start" or "ng serve", the app is working at localhost:4200

但是，当更改脚本文件或CSS类型的某些代码时，浏览器的实时刷新不会发生。这有什么不对？谢谢！

But, when changing some code for type Script file or CSS, the live refresh for browser is not happening. What's wrong here? Thanks!

推荐答案

尝试删除 node_modules 文件夹并运行 npm install 再次。这应该升级坏的npm依赖。

Try deleting your node_modules folder and running npm install again. This should upgrade a bad npm dependency.

顺便说一下，你可能还想升级到Angular CLI beta 29，因为beta 28.3一般有一些问题。如果您这样做，请注意包名称已在beta.29中从 angular-cli 更改为 @ angular / cli 。

By the way, you might also want to upgrade to Angular CLI beta 29 as beta 28.3 has a few issues in general. If you do so, note that the package name has changed in beta.29 from angular-cli to @angular/cli.
