Xcode 中的构建错误

Question

我的应用在 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。当我通过cordova plugin add https://github.com/apache/cordova-plugin-network-information

添加cordova 插件 网络信息 后，我才开始收到此错误

另外，我使用的是 cordova 4.3.0 和 Xcode 6.3.1。目前有什么办法可以解决这个问题吗？

解决方案

这对我有用：

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

Answer 1

当您添加一些插件时，ios 构建会无缘无故开始失败。大多数情况下，这与插件无关。

删除平台并重新添加它一直对我有用。

再次尝试删除并添加平台

ionic platform remove ios

ionic platform add ios
