在Heroku上使用快速應用程序崩潰的Node.js，在本地工作

Question

我有一個Node.js，它在本地運行良好，但在我嘗試在Heroku上運行時崩潰。

當我部署和去Heroku的子域：

• 的HTML負載，但在CSS不
• 當我刷新沒什麼載荷和我得到的通用應用程序錯誤
• 綜觀日誌似乎應用程序已經崩潰

任何想法爲什麼heroku不斷崩潰？最好的猜測是我的靜態文件。

下面是日誌：

這裏是我的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" 
    } 
} 

我有我的公共文件夾中的CSS和JS和這一行中app.js：

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

Answer 1

我將引用靜態文件（express.static）的代碼行移至其他代碼行上，現在它可以正常工作奧。

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 }));
