Node.js Web 服务器：
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static('public'));
app.use('/', routes);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
app.get('/Volunteer', function(req, res) {
res.sendFile(path.join(__dirname + '/Volunteer/index.html'));
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
当我部署到Heroku时，它启动得很好。我可以很好地查看主页。
如果我导航到卡布奇诺网络应用程序的地址，它会加载标准的"加载"，但没有进一步。
错误控制台打印：
Failed to load resource: the server responded with a status of 404 (Not Found)
https://myApp.herokuapp.com/Volunteer/Frameworks/Objective-J/Objective-J.js
服务器和应用程序在本地运行良好，只是不在 Heroku 上。我什至不知道如何从这里开始。我已经在Stack Overflow和Google上搜索了类似的问题，但空手而归。
以下是卡布奇诺应用程序的 HTML：

编辑***我将同一项目上传到另一个网络托管服务并遇到了同样的问题。 我还可以提供哪些其他信息来帮助诊断问题？
这是我
的错。我以符号链接的形式检查了 Objective-J 和其他框架目录。在运行应用程序并推送到 Heroku 之前，我未能在控制台中运行 jake 部署。
现在在两种环境中都能正常运行。
