我正在为我的第一个angular 2项目使用angular cli,但当我使用
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.

我检查了我的机器的所有需求,因为我有节点v5.5.0,输入了1.3.2,但它仍然生成相同的错误

我错过了什么

提前谢谢你

编辑: 今天早上我运行了
npm start
命令,它有以下错误:

The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:
Error: EPERM: operation not permitted, symlink

从问题答案来看,它与另一个使用Angular CLI自动重新加载所需端口49156的进程有关。
可以肯定的是,没有任何东西可以使用您可以请求URL的端口。如果找不到进程,重新启动可以解决问题。

我希望您已完成ng init命令,以便安装所有节点模块,能否添加有关运行
npm start
时执行的任务的信息以及angular cli的版本?请参阅@MadhuRanjan:angular cli:0.1.0节点:5.5.0 os:win32 x64以
Admin
身份运行
CMD
,然后重试。是否确定端口49156可用?您可以尝试访问URL进行检查。您的意思是什么?这个49156端口不是服务端口,我认为,它是一个测试端口。它是用于处理页面重新加载的端口,以便在您修改文件时,cli生成并在准备就绪后触发使用此端口重新加载浏览器。
