在构建我们的Target时，命令从项目源代码里的Info.plist 被copy到了Xcode/DerivedData/.../Monments.app/Info.plist 这一步骤被执行了两次。

苹果开发者论坛里有前辈遇到过这些问题

使用bundler 自动化构建脚本的时候，bundler会自动拷贝一份 info.plist 到 project.bundlePhase files。
大佬给出的方案是在buildPhase 构建脚本中加入以下语句。

#!/bin/bash
bN=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
bN=$((bN += 1))
bN=$(printf "%d" $bN)
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $bN" "$INFOPLIST_FILE"

以上方法对我来说并没有作用
我又找到stackoverflow上面相关资料，

需要把 Target -> build phases中 -> copy Bundle Resources 中的Info.plist删除掉。
程序可以正常构建成功了！
