Express.js Router + async / await函数Babel.js v6（错误：Route.post（）需要回调函数但得到[object Undefined]）

Question

我无法使快速路由器与Babel v6使用async/await函数。

它抛出了这样的错误：

MacBook-Pro-Dmitri:api dmitri$ npm start

我的.babelrc：

{
  "presets": [
    "es2015",
    "stage-0"
  ],
  "plugins": [
    "syntax-async-functions",
    "transform-regenerator",
    "transform-runtime"
  ]
}

初始文件：

require('babel-core/register');
require('babel-polyfill');
require('../src/server.js');

服务器js端点：

// uncomment to throw 
// app.get('/test1', async function () { // will throw });
app.get('/test2', function () { // no error thrown });

更新

我已经设置了一个演示回购以复制错误行为：
