问题：iOS debug没问题，一打包就报错：
Command PhaseScriptExecution failed with a nonzero exit code
解决方法如下：
在项目的Pods目录下，找到Targets Support Files->Pods-xxxx-frameworks.sh
如下：
搜索一下：
source=“ ( r e a d l i n k " (readlink " (readlink"{source}”)"
替换成:
source=“ ( r e a d l i n k − f " (readlink -f " (readlink−f"{source}”)"
重新打包即可
