nexe: nexe express4 Error: ENOENT, no such file or directory '\types\mime.types'

seems there is a bug with nexe when including express4:

app.js

var express = require('express');
console.log('hello world');

package.json

{
  "name": "nexe_express_test",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app.js"
  },
  "dependencies": {
    "express": "~4.10.8"
  },
  "nexe": {
    "input": "./app.js",
    "output": "app.exe",
    "temp": "src",
    "runtime": {
        "framework": "nodejs",
        "version": "0.12.7",
        "ignoreFlags": true
    }
  }
}

i did npm install nexe -g once and now just call nexe, relying on the package.json config, passing no command line arguments

nexe runs without errors but running the output executable gives me this error:

  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);

removing the express lines in package.json and app.js prints hello world just fine.
