javascript - 服务器未在 Node/Express 中运行

Question

我的server.js代码是:

var express = require('express');

var env = process.env.NODE_ENV = process.env.NODE_ENV || 'development';

var app = express();

app.configure(function(){

    app.set('views', ___dirname + '/server/views');
    app.set('view engine', 'jade');
});

app.get('*', function(req, res){
    res.render('index');
});
var port = 3030;
app.listen(port);
console.log('listening on Port' + port + '....');

问题是:

TypeError: undefined is not a function

您必须从过时的文档或博客中复制该代码，configure 方法已在 Express 4 中删除。

参见Migrating to Express 4具体来说

app.configure() has been removed. Use process.env.NODE_ENV or app.get('env') to detect the environment and configure the app accordingly.

快速修复:更改

app.configure(function(){
    app.set('views', ___dirname + '/server/views');
    app.set('view engine', 'jade');
});

至

app.set('views', ___dirname + '/server/views');
app.set('view engine', 'jade');
