我不明白什么是重复...任何帮助将非常感激.

Answer 1

要解决此问题,请查看来自Cordova iOS 4.5的此博客文章. http://cordova.apache.org/announcements/2017/09/08/ios-release.html

您需要删除在生成新的Ionic项目时默认安装的插件"cordova-plugin-console".现在这是适用于iOS的cordova的核心部分.

Answer 2

由于存在重复的符号,只需从目标和项目中删除"-ObjC":

构建设置 - >链接 - >其他链接器标志.

还尝试从中删除任何不需要的库

目标 - >构建阶段 - >链接二进制与库

Answer 3

这里的问题是cordova-ios @ latest.

我们可以解决这个问题:

• 首先卸载cordova-ios npm uninstall cordova-ios
• 安装cordova-ios npm install cordova-ios@4.4.0
• 之后我们应该添加平台 ionic cordova platform add ios@4.4.0
• 最后一个,运行ionic cordova build ios,使用xcode打开并使用您的设置进行构建.

Answer 4

从cordova IOS 4.5开始,它们包括cordova-plugin-console,导致插件被复制.
要解决刚刚运行:

cordova plugin rm cordova-plugin-console
