AirSim 1.8.1 + UE4.27.2 Blocks 模块编译问题

摘要本文记录了 AirSim 1.8.1 与 UE4.27.2 的环境配置及 Blocks 项目编译过程中遇到的问题。通过确认版本、重新编译 AirSim并使用 UE4 的Build.sh手动编译BlocksEditor最终成功完成AirSim和Blocks模块的编译并解决了 UE4 启动时提示模块缺失的问题。具体报错内容如下:如下airsim 报错The following moudles are missing or built with a different engine version:Blocks Airsim.Would you like to rebuild them nowEngine moudles are out of date ,and cannot be compiled while the engine is running ,Please build through your IDE1. 确认版本重新下载并编译 AirSim 1.8.1 后启动 UE4 打开 Blocks 项目时仍然出现Missing Blocks Modules一开始怀疑是 AirSim 与 UE4 版本不匹配。检查 UE4 版本cat /mnt/win_e/UE4_27/UnrealEngine/Engine/Build/Build.version确认UE4.27.2检查 AirSim 版本cd /mnt/win_e/AirSim/AirSim-1.8.1 git describe --tags --exact-match git rev-parse --short HEAD确认v1.8.1 96235148因此确认UE4.27.2 与 AirSim v1.8.1 版本匹配。2. 编译 BlocksEditor关闭 UE4Editor在 UE4 源码目录下执行cd /mnt/win_e/UE4_27/UnrealEngine ./Engine/Build/BatchFiles/Linux/Build.sh \ BlocksEditor Linux Development \ -Project/mnt/win_e/AirSim/AirSim-1.8.1/Unreal/Environments/Blocks/Blocks.uproject编译成功[4/6] Link (lld) libUE4Editor-AirSim.so [5/6] Link (lld) libUE4Editor-Blocks.so [6/6] UnrealBuildTool.exe BlocksEditor.target Total execution time: 45.59 seconds编译过程中出现部分 PhysX deprecated warning但不影响编译。3. 确认 Blocks.uprojectfind /mnt/win_e/AirSim/AirSim-1.8.1/Unreal/Environments \ -name Blocks.uproject -o -name *.uproject确认/mnt/win_e/AirSim/AirSim-1.8.1/Unreal/Environments/Blocks/Blocks.uproject使用绝对路径启动### 摘要本文记录了 AirSim 1.8.1 与 UE4.27.2 的环境配置及 Blocks 项目编译过程中遇到的问题。通过确认版本、重新编译 AirSim并使用 UE4 的 Build.sh 手动编译 BlocksEditor最终成功完成 AirSim 和 Blocks 模块的编译并解决了 UE4 启动时提示模块缺失的问题。/mnt/win_e/UE4_27/UnrealEngine/Engine/Binaries/Linux/UE4Editor \ /mnt/win_e/AirSim/AirSim-1.8.1/Unreal/Environments/Blocks/Blocks.uproject最终解决Missing Blocks Modules问题。4. 问题总结问题并非AirSim 1.8.1 与 UE4.27.2 版本不匹配而是Blocks和AirSimUnreal 模块没有针对当前 UE4.27.2 Editor 完成编译。关闭 UE4Editor 后通过Build.sh编译BlocksEditor成功生成libUE4Editor-AirSim.so libUE4Editor-Blocks.so重新启动 Blocks 项目后问题解决。
