在Heroku上托管node.js应用程序时输入错误

Question

我有我的node.js应用程序与依赖项

{
  "name": "application-name",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app"
  },
  "dependencies": {
    "express": ">=2.2.0",
    "jade": "*",
    "stylus": "*",
    "mongodb": ">= 0.9.6-7"
  }

}

它在我的localhost上工作正常

当我在heroku上托管我的节点应用程序时,我收到以下错误.

TypeError:Object#在MemoryStore.generate上的Object.uid(/app/node_modules/express/node_modules/connect/lib/utils.js:121:17)没有方法'randomBytes'(/ app/node_modules/express/node_modules/connect/lib/middleware/session.js:204:27)在Object.session [as handle]生成(/app/node_modules/express/node_modules/connect/lib/middleware/session.js:288:13)(/在Object.cookieParser上的app/node_modules/express/node_modules/connect/lib/middleware/session.js:297:7)at next(/app/node_modules/express/node_modules/connect/lib/proto.js:190:15) [作为句柄](/app/node_modules/express/node_modules/connect/lib/middleware/cookieParser.js:60:5)下一步(/app/node_modules/express/node_modules/connect/lib/proto.js:190: 15)在Object.expressInit [作为句柄](/app/node_modules/express/lib/middleware.js:31:5)下一步(/app/node_modules/express/node_modules/connect/lib/proto.js:190: 15)在Object.query [作为句柄](/app/node_modules/express/node_modules/connect/lib/middleware/query.js:44:5)

我试图逐个删除行,然后到达我删除的地方

app.use(express.session({ secret:'yodawgyo' }));

该应用程序正在给出"Hello World"响应.请参阅下面的完整代码.

var express = require('express');
var crypto = require('crypto');//for gravatar

var passport = require('passport')
  , OpenIDStrategy = require('passport-openid').Strategy
  , GoogleStrategy = require('passport-google').Strategy
  , AOLStrategy = require('passport-aol').Strategy
  , YahooStrategy = require('passport-yahoo').Strategy;;



passport.serializeUser(function(user, done) { 
  done(null, user);
});

passport.deserializeUser(function(obj, done) {
  done(null, obj);
});

var app = module.exports = express();

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.cookieParser());


//NO ISSUES WITH HEROKU IF I COMMENTED BELOW LINE   
  app.use(express.session({ secret:'yodawgyo' }));


  app.use(app.router);

});

app.get('/', function(req, res) {
  res.send("Hello World");
});

app.listen(process.env.PORT || 5000, function() {
  console.log("listening on 5000");
});

请帮帮我.

我遇到了同样的问题.它通过向package.json添加"engines"块来解决,它指示Heroku使用特定版本的节点和npm.您最有可能使用比Heroku默认值0.4.7更新版本的节点
