Npm 未满足的对等依赖angular2@2.0.0-β.14

我安装了npm软件包，并注意到以下控制台日志：

UNMET PEER DEPENDENCY angular2@2.0.0-beta.14

npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: fsevents@1.0.12
npm WARN angular2-modal@0.1.4 requires a peer of angular2@2.0.0-beta.15 but none was installed.
npm WARN ng2-bootstrap@1.0.15 requires a peer of angular2@2.0.0-beta.16 but none was installed.
npm WARN angular2-quickstart@1.0.0 No repository field.

这是什么意思

我尝试npm安装angular2，但输出是相同的

package.json依赖性

    "@angular2-material/card": "^2.0.0-alpha.2",

这似乎对我起了作用：

npm install --save rxjs@5.0.0-beta.12

这意味着包中的一个或多个依赖项仅与angular兼容angular2@2.0.0-beta.14或更高。您的package.json中列出了什么版本？在我的问题中添加了my package.json依赖项尝试执行npm卸载angular2，然后执行npm缓存清除和npm安装angular2。抱歉，我想我错过了更多信息，我收到了这个警告控制台日志，在我的问题中更新了为什么不更改（实际上是更新）angular2版本到

2.0.0-beta.17

？
