javascript - 无法弄清楚为什么应用程序没有部署到heroku

问题描述

将我的 nodejs 应用程序部署到 Heroku 时出现“内部服务器错误”。

该应用程序在本地完美运行。

这显然不是本地问题，我需要在这里更改一些东西吗？

Heroku 的错误并没有提供太多信息，但是：

-----> Creating runtime environment

       NPM_CONFIG_LOGLEVEL=error
       NODE_ENV=production
       NODE_MODULES_CACHE=true
       NODE_VERBOSE=false

.....

-----> Build succeeded!

我在 server.js 中有如下路由

app.use(express.static(__dirname + '/views'));
//app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');

//HOME
// Define routes.
app.get('/',
  function(req, res) {
    res.render('404');
  //  res.render('404', { user: req.user });
  });

路由是：
