我在我的第一个 angular 2 项目中使用 angular-cli，但是当我使用npm start命令时它会生成以下错误

Running without elevated rights. Running Ember CLI "as Administrator" increases performance significantly.
See ember-cli.com/user-guide/#windows for details.

Livereload failed on http://localhost:49156.  It is either in use or you do not have permission.

我检查了我机器的所有先决条件，因为我有节点 v5.5.0，类型为 1.3.2，但它仍然会产生相同的错误。

我错过了什么？

提前谢谢你！

编辑：我npm start今天早上运行命令，它有以下错误：

The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:

从问题答案来看，它与使用 Angular CLI 自动重新加载所需的端口 49156 的另一个进程有关。可以肯定的是，没有什么可以使用你可以请求 URL http://localhost:49156/的端口。如果找不到该进程，重新启动即可解决问题。
