当尝试将iOS平台添加到Ionic3项目时，我收到一个奇怪的错误，即较新版本的ionic-native/core不满足所有旧版本的reqs。 我有最新的内核 - 如何解决此问题以便添加平台？
ionic cordova build ios
> cordova platform add ios --save
Using cordova-fetch for cordova-ios@~4.3.1
Error: Failed to fetch platform cordova-ios@~4.3.1
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.

这是由于 npm 未在本地（而不是全局）安装的奇怪问题。
若要修复，请在尝试添加平台的目录中运行npm install npm。这还会将包更新到正确的对等依赖项版本。
然后再次运行ionic cordova platform add ios。
