Cannot compile with latest version

I've got really close, but error message is:

Node 12.2 Ubuntu 18.4

I saw the issue around downgrading to 'emscripten-1.35.0

But that doesn't seem to exist anymore

./emsdk install emscripten-1.35.0
Error: No tool or SDK found by name 'emscripten-1.35.0'.

Should work now.
