UE4.27.2源码版打包Shipping专用服务器失败，Exit Code3求助

使用GitHub编译的UE4.27.2版本，打包Shipping模式Dedicated Server时失败，返回Exit Code3。核心错误为Failed to create Config.bin file，错误触发点在MakeBinaryConfigCommandlet.cpp第102行。已尝试重新编译AutomationTool、完整编译引擎、清理项目Binaries/Intermediate目录后重新编译项目，但问题仍未解决。

错误日志如下：

排查与解决步骤 #

1. 检查权限与路径问题 #

• 项目路径C:\Program Files\Epic Games\MyProject属于系统保护目录，打包时创建Config.bin可能因权限不足失败。将项目移动到非系统目录（如D:\UEProjects\MyProject），重新生成项目文件并编译打包。
• 右键以管理员身份运行UE4编辑器或打包命令行，避免权限限制。

2. 清理Config相关缓存 #

• 删除项目目录下的Config/Saved文件夹，以及引擎目录下Engine/Config/Saved文件夹，清除旧的二进制配置缓存。
• 检查项目Config目录下的.ini文件是否有语法错误（如括号不闭合、键值对格式错误），语法错误会导致生成Config.bin时失败。

3. 调整打包配置 #

• 打开项目打包设置，确保Dedicated Server模式配置正确：
  • 临时取消勾选Use Pak File，排除Pak打包时的权限问题
  • 确认Build Configuration为Shipping，Target Platform为Windows 64-bit
• 先尝试打包Development模式的Dedicated Server，验证基础打包流程是否正常，再切换到Shipping模式。

4. 源码级修改定位具体错误 #

错误触发在MakeBinaryConfigCommandlet.cpp第102行，可修改引擎源码增加错误细节，帮助定位问题：

1. 打开D:/UnrealEngine-4.27.2-release/Engine/Source/Editor/UnrealEd/Private/Commandlets/MakeBinaryConfigCommandlet.cpp
2. 将原断言代码替换为输出具体路径和系统错误码：

// 原代码
checkf(false, TEXT("Failed to create Config.bin file"));

// 修改后
FString ConfigBinPath = FPaths::Combine(FPaths::ProjectSavedDir(), TEXT("Config/Config.bin"));
FString ErrorMsg = FString::Printf(TEXT("Failed to create Config.bin file at %s. System Error Code: %d"), *ConfigBinPath, GetLastError());
UE_LOG(LogUnrealEd, Fatal, TEXT("%s"), *ErrorMsg);

3. 重新编译引擎和AutomationTool，打包时会输出具体错误路径和系统错误码（如路径不存在、磁盘满等）。

5. 验证引擎编译完整性 #

• 确保引擎编译时勾选了Development Editor和Shipping目标，运行GenerateProjectFiles.bat后，在VS中执行Build -> Build Solution完成全量编译，避免部分模块编译不完整。
• 删除引擎目录下的Binaries和Intermediate文件夹，重新编译引擎，排除编译缓存导致的问题。
