Error: ENOENT, no such file or directory ... traceur

So after I reported issue 1 I retrograded node to v10 and now I got a different error:

path.existsSync is now called `fs.existsSync`.

fs.js:427
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

Which I got around by changing line 15 of https://github.com/filearts/plunker_run/blob/master/compilers/traceur.coffee to

runtime = fs.readFileSync(__dirname + "/../node_modules/traceur/bin/traceur-runtime.js", "utf8")

However, fixing this leads to another problem:

path.existsSync is now called `fs.existsSync`.

    throw new JS_Parse_Error(message, line, col, pos);

You can fix the uglify-js error by changing plunker_run's package.json to use uglify-js: "2.4.x"
