Question

我有一个Node.js，本地运行正常，但是当我尝试在Heroku上运行它时会崩溃。

当我部署并转到heroku子域时：

HTML加载但CSS不
当我刷新任何负载并且我得到通用应用程序错误
查看日志似乎应用已崩溃

为什么heroku不断崩溃的任何想法？最佳猜测与我的静态文件有关。

以下是日志：

这是我的package.json：

{
  "name": "myapp",
  "version": "0.0.1",
  "engines": {
    "node": "0.10.26",
    "npm": "1.4.20"
  },
  "scripts": {
    "start": "node app.js"
  },
  "dependencies": {
    "express": "~4.2.0",
    "body-parser": "^1.4.3",
    "node-compass": "0.2.3",
    "ejs": "~1.0.0",
    "express-ejs-layouts": "~1.1.0",
    "mailgun-js": "^0.5.1"
  }
}

我在公共文件夹中有我的css和js，并且在app.js中有这一行：

app.use(express['static'](path.join(__dirname, 'public')));

Answer 1

我将引用静态文件（express.static）的代码行移到了其他代码行之上，现在它在Heroku上工作正常。

app.use(express.static(__dirname + '/public'));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('layout', 'layout'); // defaults to 'layout'
app.use(require('node-compass')({mode: 'expanded'}));
app.use(expressLayouts);
app.use(bodyParser.urlencoded({ extended: false }));

在Heroku上使用快速应用程序崩溃的Node.js在本地工作
