Question

在我的Ionic 2项目中，我尝试使用npm install ng2-pdf-viewer --save

导致： ├──UNMETPEER DEPENDENCY @ angular / core @ 2.1.1

└─┬ng2-pdf-viewer@1.0.1

└──@ types / pdf @ 0.0.31

npm WARN ng2-pdf-viewer@1.0.1需要@ angular / core @ ^ 2.2.1的同伴但没有安装。

我该如何解决这个问题？

我的package.json包括：

"dependencies": {
    "@angular/common": "2.1.1",
    "@angular/compiler": "2.1.1",
    "@angular/compiler-cli": "2.1.1",

要使用ng2-pdf-viewer，您需要angular 2.2.1或更多。您可能必须将package.json中的所有角度依赖关系[angular / core，http，compiler-cli等]更新为2.2.1^并检查。您可以参考最新的离子2包依赖项here。

如何安装@ angular / core @ ^ 2.2.1＆＃39;？
