Question

当我尝试将angular2升级为RC时，我收到以下错误。 JWT依赖于RC，所以我不得不更新到@angular

M:\workspace\Angular2StartKit>npm install

在Angular2 RC1中，您需要在package.json文件中指定一组子包，而不是像Beta版本那样的大包：

{
  (...)
  "dependencies": {
    "@angular/common": "2.0.0-rc.1",
    "@angular/compiler": "2.0.0-rc.1",
    "@angular/core": "2.0.0-rc.1",
    "@angular/http": "2.0.0-rc.1",
    "@angular/platform-browser": "2.0.0-rc.1",
    "@angular/platform-browser-dynamic": "2.0.0-rc.1",
    "@angular/router": "2.0.0-rc.1",
    "@angular/router-deprecated": "2.0.0-rc.1",
    "@angular/upgrade": "2.0.0-rc.1",
    (...)
  }
}

无法更新到Angular2 RC @ angular @ 2.0.0-rc.1
