我在角度2应用程序中使用@angular/router路由器模块。我再次运行npm install并收到以下错误消息angular/core has no NgModuleFactoryLoader。我在网上找到了以下内容：
npm remove @angular/router --save // will remove the RC router
npm install @angular/router@3.0.0-alpha.7 --save // will install the latest router

这解决了我的问题，但在删除我的node_modules并运行npm install后，问题又回来了。
我的依赖项：
"dependencies": {
"@angular/common": "^2.0.0-rc.5",
"@angular/compiler": "2.0.0-rc.5",
