React/react router/heroku的问题（很可能是在heroku上出了问题）。

我正在按照这个很棒的教程进行操作：https://medium.com/@patriciolpezjuri/using-create-react-app-with-react-router-express-js-8fa658bf892d#.y77yjte2j

一切都进行得很顺利，直到我将它发布到heroku并尝试导航到https://appname.herokuapp.com/about，我收到了一个404 Not Found/nginx错误。当然，根据教程，应该显示一个关于页面。

React router在heroku上不起作用，我无法弄清楚为什么。

我尝试修改server/app.js文件，如在这里建议的：React routes are not working in facebook's create-react-app build

// server/app.js
const express = require('express');
const morgan = require('morgan');
const path = require('path');
const app = express();
console.log('hi from /src/server.js')
// 设置日志记录
app.use(morgan(':remote-addr - :remote-user [:date[clf]] ":method :url HTTP/:http-version" :status :res[content-length] :response-time ms'));
// 提供静态资源
app.use(express.static(path.resolve(__dirname, '..', 'build')));
// 始终返回主要的index.html，这样react-router可以在客户端渲染路由
app.get('/about', (req, res) => {
  console.log('hi from app.get.about')
  console.log(req)
  console.log(res)
  res.sendFile(path.resolve(__dirname, '..', 'build', 'index.html'));
});
app.get('/*', (req, res) => {
  console.log('hi from app.get')
  console.log(req)
  console.log(res)
  res.sendFile(path.resolve(__dirname, '..', 'build', 'index.html'));
});
module.exports = app;

但是它不起作用，也没有在控制台中记录任何内容：

这就是我卡住的地方。我熟悉Express，并且之前在heroku上使其工作过，但这是一个完全不同级别的噩梦。我明白这不是服务器端路由，而是React在单个index.html页面中进行的路由。但是如果我可以在本地机器上让它工作，为什么在Heroku上不起作用？
