Empty WebGL project fails to build

Unity Engine

I can’t manage to build even an empty WebGL project on Unity 2017.1.0f3. I’m attaching the Console output in the file.

You can’t build for WebGL in that version.

Which version should I use? Is 5.6.3 one that will work?

EDIT: I’ve downloaded the 2017.1.0p3 patch from yesterday, it builds the WebGL but the output game is empty i.e. only displays white page.

I can build from both versions… 0f3 and 0p3.

But i remember that this problem already existed in earlier versions. You can try save the build into the project folder.

Edit: you can also try to reinstall python.
