Cocoapods库的架构armv7的未定义符号

我偶然发现了我需要处理的项目中的问题。该项目使用Cocoapods来管理其库。我pod install像往常一样开始运行，但是xcode给我错误。我得到了Undefined symbols for architecture armv7你可以在下面的图片中看到：

所有这些符号都是我在项目中使用的库。例如。AFNetworking，RNBlurModalView。我试图从项目中删除所有与Cocoapods相关的文件并pod install再次运行，但是仍然不能解决问题。

到目前为止，我所做的是：

• 清理项目，然后重新构建。
• 删除与Cocoapods相关的文件，然后pod install再次运行。
• 试图将类添加到Project Target的“编译源”中，但不能这样做。该类在Pods工作区中。
• 将Build Active Architecture仅从设置YES为NO。

我也尝试了相同问题的解决方案，但没有一个对我有用。

如果有帮助，我正在使用xCode6和Cocoapods 0.34.4。该项目的有效架构为armv7 and armv7s。

更新：运行时pod install --verbose
