Xcode 中的构建错误

Question

我的应用程序在 Chrome/Safari 网络浏览器中运行良好，但是当我尝试从 Xcode 运行它时，出现错误。我只是在通过 cordova plugin add https://github.com/apache/cordova-plugin-network-information

添加 cordova 插件 网络信息 后才开始出现此错误

此外，我使用的是 cordova 4.3.0 和 Xcode 6.3.1。目前有什么方法可以克服这个问题吗？

解决方案

以下是对我有用的方法：

$ ./platforms/ios/cordova/clean
$ sudo ionic plug remove cordova-plugin-network-information
$ sudo ionic plugin add https://github.com/apache/cordova-plugin-network-information
$ sudo ionic build ios

Answer 1

当您添加一些插件时，ios 构建开始无缘无故地失败。大多数时候这与插件无关。

删除平台并重新添加回来一直对我有用。

再次尝试删除和添加平台

ionic platform remove ios

ionic platform add ios
