Other build(For PC, Android) is works. I tried reinstal Unity and Visual Studio, but still errors.
How can I fix it?

Thank you very much.

 

I try update Visual studio from version 2015 to Visual 2017 and errors in Unity was changed.

I see the problem to run Node.js environment

Code (Boo):

1. CRITICAL:root:The JavaScript shell used for compiling (['C:/Program Files/Unity/Editor/Data\\Tools\\nodejs\\node.exe', '--stack_size=8192', '--max-old-space-size=2048']) does not seem to work, check the paths in C:\Program Files\Unity\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\emscripten.config

But when I try to execute this line
C:/Program Files/Unity/Editor/Data/Tools/nodejs/node.exe --stack_size=8192 --max-old-space-size=2048 C:\\Program Files\\Unity\\Editor\\Data\\PlaybackEngines\\WebGLSupport\\BuildTools\\Emscripten\\src\\hello_world.js
manually it works fine.
