Dependencies 如何安装'peer of@angular/core@^2.2.1'？

在我的爱奥尼亚2项目中，我尝试npm安装ng2 pdf查看器-保存

其结果是： ├── 未满足的对等依赖@angular/core@2.1.1

└─┬ ng2 pdf-viewer@1.0.1

└── @类型/pdf@0.0.31

npm警告ng2 pdf-viewer@1.0.1需要@angular/core@^2.2.1的对等方 但没有安装

我怎样才能解决这个问题

My package.json包括：

"dependencies": {
    "@angular/common": "2.1.1",
    "@angular/compiler": "2.1.1",
    "@angular/compiler-cli": "2.1.1",
    "@angular/core": "2.1.1",
    "@angular/forms": "2.1.1",
    "@angular/http": "2.1.1",
    "@angular/platform-browser": "2.1.1",
    "@angular/platform-browser-dynamic": "2.1.1",
    "@angular/platform-server": "2.1.1",
    "@ionic/storage": "1.1.6",
    "@types/moment": "^2.13.0",
    "font-awesome": "^4.7.0",
    "ionic-angular": "2.0.0-rc.3",
    "ionic-native": "2.2.3",
    "ionicons": "3.0.0",
    "jquery": "^3.1.1",
    "moment": "^2.17.1",
    "ng2-pdf-viewer": "^1.0.1",
    "pdfjs-dist": "^1.6.483",
    "rxjs": "5.0.0-beta.12",
    "ts-md5": "^1.2.0",
    "zone.js": "0.6.26"
  }

要使用ng2 pdf viewer，您需要具有angular 2.2.1或更高版本。 您可能需要将package.json中的所有角度依赖项[angular/core、http、compiler cli等]更新为2.2.1^，并进行检查。

您可以参考最新的ionic 2软件包依赖项。
