1) Target 'EMEatMain' has create directory command with output '/Users/qyt/Library/Developer/Xcode/DerivedData/EMEatMain-aicawnzyamsdrwexxdyyhgjfzyzm/Build/Products/Debug-iphonesimulator/EMEatMain.app'
2) That command depends on command in Target 'EMEatMain': script phase “[CP] Copy Pods Resources”

分析error内容：
错误发生在 Copy Pods Resources，并且与 outpu t有关，应该是使用了cocoapods 导致的，尝试删除该项目target - > Copy Pods Resources - > Output Files，成功解决问题。
删除Output Files
