缺失的依赖性，离子2中未满足的同伴依赖性

Question

我只想将背景地理位置添加到我的离子2应用程序中：

 npm install --save @ionic-native/background-geolocation

我得到错误：

> ├── @ionic-native/background-geolocation@3.5.0  ├── UNMET PEER
> DEPENDENCY @ionic-native/core@^3.1.0 └── UNMET PEER DEPENDENCY
> rxjs@5.0.0-beta.12
> 
> npm WARN @ionic-native/background-geolocation@3.5.0 requires a peer of
> @ionic-native/core@^3.1.0 but none was installed. npm WARN
> @ionic-native/background-geolocation@3.5.0 requires a peer of
> rxjs@^5.0.1 but none was installed.

我该如何修复？

Answer 1

同伴依赖性只是警告，它不会破坏您的构建，您需要的同伴依赖项是@ionic-native/core@^3.1.0和rxjs@^5.0.1

我看到您有"rxjs": "5.0.0-beta.12"将其更改为"rxjs": "^5.0.1"

至于@ionic-native/core，我看到您有"@ionic-native/core": "^3.5.0"，并且是同行依赖性需求的后期版本。
