一、问题：可能是git原因

因为之前使用了git但是后来不用了，打包时候发现失败了

 UnrealBuildTool.GuardedMain: Command line: "E:\UE4\UE_4.21\Engine\Binaries\DotNET\UnrealBuildTool.exe" yueQiuChe Win64 Shipping -Project=G:\Project\guShi\_qianYanKeJi\yueQiuChe\Scripts\yueQiuChe200\yueQiuChe.uproject  G:\Project\guShi\_qianYanKeJi\yueQiuChe\Scripts\yueQiuChe200\yueQiuChe.uproject -NoUBTMakefiles  -remoteini="G:\Project\guShi\_qianYanKeJi\yueQiuChe\Scripts\yueQiuChe200" -skipdeploy -Manifest=G:\Project\guShi\_qianYanKeJi\yueQiuChe\Scripts\yueQiuChe200\Intermediate\Build\Manifest.xml -NoHotReload -log="C:\Users\andLxs\AppData\Roaming\Unreal Engine\AutomationTool\Logs\E+UE4+UE_4.21\UBT-yueQiuChe-Win64-Shipping.txt"

答：

1、将之前里面的关于git文件全部删除

2、编译一下，然后打包（没有删除git文件之前编译都会失败）
