我正在尝试使用 SMP SDK 3.O PL3 创建适用于 iOS 的 Fiori 客户端。在某些时候，它会尝试获取一个不存在的插件：Fetching plugin "kapsel-plugin-inappbrowser" via npm
我不明白为什么。插件的源文件都在那里，就像其他插件一样：
$ cordova platform add ios --searchpath /Users/Pieter/SAP/MobileSDK3/KapselSDK/plugins

Fetching plugin "kapsel-plugin-inappbrowser" via npm
Failed to install 'kapsel-plugin-authproxy':CordovaError: Failed to fetch plugin kapsel-plugin-inappbrowser via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.
