我正在编写一个使用express并希望swig用作渲染引擎的应用程序。我以前用过，很好用，但是版本变了，我不知道该怎么办。这是我到目前为止所写的：
网页.js
var express = require('express');
var app = express();
var swig = require('swig'); // rendering engine
app.engine('html', swig.renderFile);
app.set('view engine', 'html');
app.set('views', __dirname + '/views');
app.use(express.static(__dirname + '/public'));
app.use(express.bodyParser());
app.use(express.logger());
app.get('/', function (req, res) {
console.log('--> root#home');
res.render('root/home.html', { x: 1 });
console.log('<-- root#home');
});
var port = process.env.PORT || 5000;
app.listen(port, function() {
console.log("Listening on " + port);
});
意见/根/home.html
You are at root#home, x = {{ x }}
现在的问题是，当我启动服务器并localhost:5000/在浏览器中打开它时，它会正确显示Your are at root#home, x = 1。但是在我提出第二个请求后localhost:5000/，它就挂了……没有回复。在日志中我看到请求进入函数并退出它
$ foreman start

15:19:17 web.1 | --> root#home // ** first time **
