Angular app永远不会启动

Question

我正在尝试使用Angular 2，但是当我尝试使用命令ng serve启动服务器时，没有任何反应。该命令不执行任何操作，没有错误消息，没有状态消息，任何内容。

我在Windows 10 64位上运行，我认为我的计算机可能存在问题，我在虚拟机中尝试过并且工作正常。如果它是相关的，我正在使用vpn。

我已经检查过端口是否正在使用中。 我一直在管理员模式下尝试使用cmd，但没有。

有人可以帮助我吗？ NodeJS版本6.11.5。 Angular / cli版本1.5.0。 NPM版本3.10.10。

Answer 1

可能的解决方案： -

       1) Uninstall node.js and install latest version of node.js > 8.

      Try to install Visual studio code or other ide's. 

       2)Delete node MOdules and run command- npm install in visual studio code- 'terminal'
       3)Your angular-cli  is latest, so no need to install again.

尝试清理并重新安装angular-cli

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest
