CocoaPods 错误 target overrides the OTHER_LDFLAGS...

        [!] The `Paopao [Debug]` target overrides the `PODS_ROOT` build setting defined in `Pods/Target Support Files/Pods/Pods.debug.xcconfig'. This can lead to problems with the CocoaPods installation
- Use the `$(inherited)` flag, or
- Remove the build settings from the target.

- Remove the build settings from the target.

 [!] The `Paopao [Release]` target overrides the `PODS_ROOT` build setting defined in `Pods/Target Support Files/Pods/Pods.release.xcconfig'. This can lead to problems with the CocoaPods installation
- Use the `$(inherited)` flag, or

这种警告是不能忽视的，它带来的直接后果就是无法通过编译。直接报错：

 ld: symbol(s) not found for architecture x86_64 clang:
 error: linker command  ........

而产生此警告的原因是项目 Target 中的一些设置，CocoaPods 也做了默认的设置，如果两个设置结果不一致，就会造成问题。

我想要使用 CocoaPods 中的设置，分别在我的项目中定义PODS_ROOT 和 Other Linker Flags的地方，把他们的值用$(inherited)替换掉，进入终端，执行

   pod update --verbose --no-repo-update
