【问题描述】：

我正在使用 Ionic 2 开发一个混合应用程序，我想添加平台 iOS 但无法添加平台。

我也尝试使用以下命令更新 npm，但它不起作用。命令：

npm 更新 -g

下面是我的终端输出，显示了我收到的错误，有人可以推荐解决此问题的解决方案吗？

Using cordova-fetch for cordova-ios@~4.5.1

Error: Failed to fetch platform cordova-ios@~4.5.1
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.
