试图升级到Angular2 rc1,但似乎npm无法下载软件包:

{
  "name": "App",
  "version": "1.0.0",
  "license": "MIT",
  "dependencies": {
    "@angular/common": "2.0.0-rc.1",
    "@angular/compiler": "2.0.0-rc.1",
    "@angular/core": "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/http": "2.0.0-rc.1",

    "systemjs": "0.19.27",
    "es6-shim": "^0.35.0",
    "reflect-metadata": "^0.1.3",
    "rxjs": "5.0.0-beta.6",
    "zone.js": "^0.6.12"
  },
  "devDependencies": {
     "gulp": "3.9.1",
     "gulp-rimraf": "0.2.0",
     "gulp-uglify": "1.5.3",
     "gulp-concat": "2.6.0",
     "gulp-cssmin": "0.1.7",
     "gulp-replace": "0.5.4"
   }
}
