Question

当我因某种原因尝试安装新软件包时，npm会删除与angular cli相关的所有软件包。当我重新安装angular cli时，我收到以下错误消息：

C:\SomeApp\Main\WebUI>ng serve

The "@angular/compiler-cli" package was not properly installed.
Error: The "@angular/compiler-cli" package was not properly installed.

遇到此问题时，您可以先尝试更新角度cli。

https://github.com/angular/angular-cli#updating-angular-cli

请务必运行此命令。

删除node_modules
npm cache clean
npm install

还要确保这是package.json文件中的依赖项，例如

  "@angular/cli": "1.0.0",
  "@angular/compiler-cli": "^4.0.0",

希望它有所帮助..

我昨天刚遇到同样的错误。在尝试了几乎所有可能的解决方案一天后，对我有用的是：npm install -g -f angular-cli

它将用@ angular-cli替换@ angular / cli来解决现在的问题，然后你可以将它更新到新版本。另请在此问题上查看this link as it has great info。

安装包后没有编译的角度cli
