Webgl build with Brotli compression fails

Hello everyone .-

I have been trying to deploy a Webgl build to the server, but normal gzip compression doesnt run at my server url or domain, now i have switched to Brotli compression Format at Player Publishing Settings, but it throws to me 3 errors the first one is python realated.-

Code (csharp):

1.  
2. Failed running python "/home/jorgecg/Unity/Hub/Editor/2019.1.0f2/Editor/Data/PlaybackEngines/WebGLSupport/BuildTools/Brotli/python/bro.py" -o "/backup/Unity Projectos/Unity Projectos/Actualizado 21Abril2019/BinaryWritter/Temp/StagingArea/Data/Output/Build/BinaryWritter.data.unityweb.compressed" -i "/backup/Unity Projectos/Unity Projectos/Actualizado 21Abril2019/BinaryWritter/Temp/StagingArea/Data/Output/Build/BinaryWritter.data.unityweb" --comment "UnityWeb Compressed Content (brotli)"

Oh btw im on Linux, i saw a thread, this one https://issuetracker.unity3d.com/is...-python-lacks-permissions-for-group-and-other in which it explains how to give permissions to the python directory and also to the bro.py python file, i have even created "executable" the file, but the above error persists. I imagine i need to fix this error before the other 2 ones i have while building to Webgl. Thank in advance.

 

Hi!,

Any news on this, I'm facing the exact same problem and can't really figure out why?

Thanks in advance!

 

I was struggling with this for quite a while, I "solved" it by renaming the MacOS egg and creating a symlink to the Linux egg with the name of the previous MacOS egg...
I honestly don't know why the bro.py tries to load the MacOS egg during the import. There might be something messed up with the environment the Editor tries to start the python script

In case it was a bit unclear

cd $UNITY_EDITOR_DIR/Editor/Data/PlaybackEngines/WebGLSupport/BuildTools/Brotli/dist
mv Brotli-0.4.0-py2.7-macosx-10.10-x86_64.egg Brotli-0.4.0-py2.7-macosx-10.10-x86_64.egg.bkup
ln -s $PWD/Brotli-0.4.0-py2.7-linux-x86_64.egg Brotli-0.4.0-py2.7-macosx-10.10-x86_64.egg

 

I suggest to switch from Brotli to gzip.
File -> Buld Settings -> Player Settings -> Player -> Publishing Settings -> Compression Format -> Gzip

 

Same problem here. I don't want to do manual stuff in the engines, so I'd rather change de compression format for the moment.

Code (CSharp):

1. #if UNITY_EDITOR_LINUX
2.         PlayerSettings.WebGL.compressionFormat = WebGLCompressionFormat.Gzip; // Brotli not working on linux compilation at the moment. See (https://forum.unity.com/threads/webgl-build-with-brotli-compression-fails.666823/)
3. #else
4.         PlayerSettings.WebGL.compressionFormat = (devMode ? WebGLCompressionFormat.Gzip : WebGLCompressionFormat.Brotli);
5. #endif

Please unity team, do you have any input on this ?
Thanks

 

this leads to another problem then

Firefox also doesn't support Broti compression and fails at the window, while Chrome launches fine. Switching to gzip as suggested works.

 

gzip works okay on desktop, but then fails if the game runs as WebGL from an iPad browser I wish there was a catch-all cross platform solution
