Question

我遇到了一些不再使用NODE.js的中间件问题我就是这样做的：

Node js Error: Most middleware (like session) is no longer bundled with Express and must be installed separately

但我仍然遇到同样的错误：＆＃34;大多数中间件都是bla bla bla ...＆＃34;

var express = require('express');
var mongoose = require('mongoose');
var path = require('path');
var bodyParser = require('body-parser');
var config = require('config');
var session = require('express-session');

var app = express();
var IS_DEV = (app.get('env') === 'development');
var MongoStore = require('connect-mongo')(express);

app.use(session({
  secret: config.get('session:secret'),
  key: config.get('session:key'),
  cookie: config.get('session:cookie'),
  store: new MongoStore({mongoose_connection: mongoose.connection})
}));

已安装软件包，我在node_modules文件夹中看到它。而且我没有看到任何错误：session is undefined我做错了什么？

顺便说一下express-error-handler包

windows 8.1
node 4.4.0
mongodb 3.2.4
npm 2.14.20
express 4.13.4

性反应：

Error: Most middleware (like session) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

由于您使用的是Express 4，connect-mongo的设置不正确。

应该是：

var session = require('express-session');
...
var MongoStore = require('connect-mongo')(session);
                                          ^^^^^^^ not `express`

请参阅the documentation。
