heroku错误：ENOENT，stat'/app/build/index.html'

Im trying to deploy to heroku but Im getting Error: ENOENT, stat '/app/build/index.html' when I go to my address. Otherwise the application deployment does not give me any error. Can somebody explain what Im doing wrong. Here is my code and code structure.

我试图部署到heroku但我得到错误:ENOENT,stat'/app/build/index.html'当我去我的地址。否则,应用程序部署不会给我任何错误。有人可以解释我做错了什么。这是我的代码和代码结构。

server.js

var express = require('express'),
    server = express(),
    bodyParser = require('body-parser'),
    logger = require('morgan'),
    methodOverride = require('method-override'); // for heroku

var port = process.env.PORT || 5000;

server.use(express.static(__dirname + '/build'));
server.use('/src', express.static(__dirname + '/build/src'));       // js
server.use('/assets', express.static(__dirname + '/build/assets')); // css, images
server.use('/vendor', express.static(__dirname + '/build/vendor')); // other

server.use(logger('dev'));

server.get('/', function(req, res, next) {
  res.sendfile('index.html', { root: __dirname + '/build' });
});

server.listen(port, function() {
  console.log("Listening on " + port);
});

#1

Figured it out. It was my .gitignore file where I included the /build folder.

弄清楚了。这是我的.gitignore文件,其中包含/ build文件夹。

#2

Try somthing like this:

尝试这样的事情:

res.sendfile( __dirname + '/build/index.html' );
