Angular2 CLI 错误@angularcompilercli包未正确安装

我在做一个Angular 2项目.现在try 在当前项目中安装Angular CLI，方法如下

npm install --save-dev @angular/cli@latest
npm install

问题是当运行ng serve时，我收到错误

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