If this error occurs, it's because SCons is not detecting your Emscripten setup. You most likely need to run the ./emsdk env activate
command every time you wish to build Godot in a new terminal session.
Thanks for replying, can you tell me how I do it, I am using Visual Studio terminal to compile, just do this command first or do it together with build scons command. I'm a little new to the command line, I'm using windows.
