今天，90％的免费日我想测试一些“技术”，我发现heroku和nodeJS将是一个很好的主题。
本教程使用ejs模板，我想将它们更改为jade（不转换，只使用jade），因此我在项目中添加了pug。
请查看我的index.js（node 6.2.0）
var express = require('express');
var app = express();
// const RouteService = require('./server/services/RouteService');
app.set('port', (process.env.PORT || 5000));
app.use(express.static(__dirname + '/public'));
app.set('view engine', 'pug')
app.set('views', __dirname + '/views');
// RouteService.registerRoutes(app);
app.get('/', function(request, response) {
response.render('/pages/index', { title: 'Hey Hey Hey!', message: 'Yo Yo'});
});
app.listen(app.get('port'), function() {
console.log('Node app is running on port', app.get('port'));
});
所以这主要是heroku模板。index.js在主文件夹中是./index.js，index.jade是./views/pages/index.jade。
错误（本地与node index.js和heroku（同一命令））是
Error: Failed to lookup view "/pages/index" in views directory "/home/daniel/Pulpit/crystal-fan-prototype/views"

我觉得我有一个我无法识别的非常微不足道的问题，谢谢你的建议！
