Can not build for html5

Hi i am using Unreal Engine 4.8.1 downloaded via Epic Games Launcher. I can not compile nor Launch 3rd person template to html5. If i click on compile > html5 it takes me to a webpage with info on how to set up emscripten and python. In launch option there is no Firefox browser (i have 32bit and 64bit Nightly). The “html5Engine.ini” for 4.8 version is set, emscripten is installed and working, python is installed and working. I restarted engine many times, restarted pc but same thing happends. Only once i got a option to Launch to Firefox from “Project Launcher” and i got this error:
Program.Main: ERROR: Exception in UnrealBuildTool: ERROR: GetBuildPlatform: No BuildPlatform found for HTML5.

What am i doing wrong?

You should be able set two relevant things in Project Settings → HTML5 SDK.

you would need to setup 2 things - Location of your 64 bit python.
and location of your emscripten SDK.

Hi, it is set, same thing happends

you should be able to use the drop down to set the version ( “latest” etc ). Also can you make sure that the emscripten directories actually exists - ie .C:/Program Files/Emscripten/emscripten/*

If you don’t have the C:/Program Files/Emscripten/emscripten/ folder, this likely means you haven’t compiled emscripten for your computer yet. Here are instructions for getting and installing it once you’ve already downloaded the emsdk. It also helps to run the command line as an administrator for installation.

I’d installed Emscripten with the web installer (as administrator), and python / nightly + updated the ini file as described on the UE4 getting started page. Installed tappy chicken under 4.8.3 but getting “No Build Platform found for HTML5” when trying to launch.

After reading this, I noticed I don’t have the Emscripten/emscripten folder so I tried to install the SDK manually using the commands on the page you linked above - “emsdk install latest” wants cmake installed as admin (which I installed, but it still fails).

Is it normal to have this much trouble? Would be good if the documentation page could be updated to reflect the steps for running tappy chicken at least in 4.8+…

After searching around more I found this forum post. I was able to get it working by download the offline installer for emscripten 1.27. Tappy Chicken now works!

Would still be great if the official getting started page could be updated to reflect current steps.
