I really would like to try HTML5 on unreal but its instalation is very hard. After many hours of problems, I can finaly try a packaging but unfortunately it doesn’t work. An error emcc: error: The temporary directory error_temp_dir_not_found appears for the 511 actions to build :

Someone can help me ? What is The temporary directory ? what is it for? how to correct its path? thanks in advance, I apologize for my bad english
I managed to work around this error by creating a folder tmp at this location : ue4-4.24.3-html5\Engine\Platforms\HTML5\Build\emsdk\emsdk-1.39.18\tmp But now, I have other problems

Before these two errors, I had other errors when launching GenerateProjectFiles.bat
Node and python did not find because their directory name did not match.
it was stuck here :
ue4-4.24.3-html5\Engine\Platforms\HTML5\Build\emsdk\emsdk-1.39.18\node\12.18.1_64bit
ue4-4.24.3-html5\Engine\Platforms\HTML5\Build\emsdk\emsdk-1.39.18\python\3.7.4_64bit
These directories was of a more recent version, the script “GenerateProjectFiles.bat” was looking for an older version.
So I renamed my directories for him to find node.exe and python.exe
It was maybe a bad idea ? My current problem may be related to this bad manipulation ?
Ya I think so. It’s better to rename the paths in the source files but even then you will struggle for a while probably because the community repo you are using is not maintained. It’s possible, I currently use that repo but it’s not that easy to setup and you will have to fiddle with things. If you can use the official 4.23 version, you will have an easier time.
I finally managed to package my project by installing python in 3.7.4_64bit version and node js in 12.18.1_64bit version. Everything work fine !
for those who are in the same problem as me, with node js not found and python not found errors when generateProcjectFiles.bat : Install them in the specified versions by the path then restart HTML5Setup.sh
