Unreal Engine打包项目

1. 官网指导：

https://docs.unrealengine.com/zh-CN/Engine/Basics/Projects/Packaging/index.html

在Unreal Editor界面中操作进行打包时，在linux机上遇到了问题，首先是Error：

Error: declaration shadows a variable in namespace 'Chaos' 

用了以下链接中的方法解决后：

https://github.com/microsoft/AirSim/issues/2617

仍然存在error：

LogOutputDevice: Error: === Handled ensure: ===

未能解决，总是打包失败。

2. 按照AirSim仓库的issue中的线索：

Error packaging Blocks project on linux · Issue #1034 · microsoft/AirSim · GitHub

在电脑的/data/AirSim/目录下输入：

$UE4_ROOT/Engine/Build/BatchFiles/RunUAT.sh BuildCookRun                 -project="$(pwd)/Unreal/Environments/Blocks/Blocks.uproject"                 -nop4 -nocompile -build -cook -compressed -pak -allmaps -stage                 -archive -archivedirectory="$(pwd)/Unreal/Environments/Blocks/Packaged/Development"                 -clientconfig=Development -clean -utf8output

经过一定时间的等待，成功在Unreal/Environments/Blocks/Packaged/Development文件夹下生成了ubuntu下可用的Unreal程序包。在生成程序包的电脑下可用。

3. 在另一计算机中按照2中的命令首先对ABlock进行打包，得到了error：

Cannot open assembly 'AutomationTool.exe': No such file or directory.RunUAT ERROR: AutomationTool was unable to run successfully.

再使用同样的命令对自带Blocks进行同样的操作，也出现error。

4. 在3中的计算机中后续进行过的操作有：

a. 在unreal editor界面中对ABlock进行打包（失败）

b. 对hp机中linux下的unreal进行如步骤1中的修改；在unreal下重新make；

c. 使用2中的命令对Blocks进行打包，成功，可以独立运行packaged环境；

d. 使用2中的命令对ABlock进行打包，失败；

    且：不使用#2877的修改，则在命令行打包时返回一个与weather option有关的错误；使用#2877的修改，则在打包时就会返回和issue#2957相似的Name 'Dev-Core' PackageVersion 4  MaxExpected 3错误。

结论：暂时放弃打包，发布可编辑版本ABlock环境。
