Question

我试图部署到heroku但我到达Error: ENOENT, stat '/app/build/index.html'我的地址时得到了.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() {

Answer 1

弄清楚了.这是我的.gitignore文件,其中包含了该/build文件夹.
