[s20208413]

This is main.js:

var path, main;

path = require('path');

main = async function() {
  console.log(path.join('a', 'b'));
};

main();

noderify does not work:

$ node --version
v8.8.1
$ node node_modules/.bin/noderify --version
3.0.2
$ node main.js
a/b
$ node node_modules/.bin/noderify main.js > bundle.js
events.js:182
      throw er; // Unhandled 'error' event
      ^
