Heroku，node.js，服务器崩溃与错误：大多数中间件（如记录器）不再与Express捆绑在一起，必须单独安装 [英] Heroku, node.js, server crash with Error: Most middleware (like logger) is no longer bundled with Express and must be installed separately

问题描述

我尝试将我的应用程序部署到heroku服务中，但在推送文件后，日志会给我这个错误：
错误：大多数中间件（如记录器）不再与Express捆绑在一起，必须单独安装。 / p>

我的package.json是

  {
依赖关系：{
connect：3.0.0-rc.2，
express：^ 4.1.1，
express-logger：0.0.2 ，
gzippo：^ 0.2.0，

解决方案

  // package。 json（Express 4）
 ... 
依赖关系：{
express：〜4.0.0，
morgan：〜1.0.0 ，
body-parser：〜1.0.0，
method-override：〜1.0.0
} 
 ... 
  

示例代码（详情请参阅文档）：

  // server.js（Express 4）
 var express = require（'express'）; 
 var morgan = require（'morgan'）; 
 var bodyParser = require（'body-parser'）; 
 var methodOverride = require（'method-override'）; 
 var app = express（）; 
  

  //替换您的Express 3代码，从
 // 
 // app.use（express.logger（'dev'））; 
 // app.use（express.bodyParser（））; 
 // app.use（express.methodOverride（））; 
 // 
 //至：
 app.use（morgan（'dev'））; //将每个请求记录到控制台
 app.use（bodyParser（））; //从POST中的html中获取信息
 app.use（methodOverride（））; //模拟DELETE和PUT 
 app.listen（8080）; 
  

另一种选择是将package.json中的express版本更改为使用Express 3 。

express：〜3.0.0

I try to deploy my app into heroku service, but after push the files the log give me this error: Error: Most middleware (like logger) is no longer bundled with Express and must be installed separately.

My package.json is

{
   "dependencies":{
      "connect":"3.0.0-rc.2",
      "express":"^4.1.1",
      "express-logger":"0.0.2",

      "logfmt":"^1.1.2"
   },
   "devDependencies":{
      "connect":"3.0.0-rc.2",
      "grunt":"~0.4.1",
      "grunt-autoprefixer":"~0.4.0",

      "karma-ng-scenario":"^0.1.0",
      "load-grunt-tasks":"~0.4.0",

   },
   "engines":{
      "node":">=0.10.0"
   },
   "name":"eversnap",
   "scripts":{
      "test":"grunt test"
   },
   "version":"0.0.1"
}

解决方案

It looks like Express 4 is upgraded from Express 3 but the json (and maybe code too) is not.

// package.json (Express 4)
...
  "dependencies": {
    "express": "~4.0.0",
    "morgan": "~1.0.0",
    "body-parser": "~1.0.0",
    "method-override": "~1.0.0"
  }
...

sample code (refer to documentation for full details):

// server.js (Express 4)
var express        = require('express');
var morgan         = require('morgan');
var bodyParser     = require('body-parser');
var methodOverride = require('method-override');
var app            = express();

// Replace your Express 3 code, from
//
// app.use(express.logger('dev'));                 
// app.use(express.bodyParser());
// app.use(express.methodOverride()); 
//
// to:
app.use(morgan('dev')); // log every request to the console
app.use(bodyParser()); // pull information from html in POST
app.use(methodOverride());  // simulate DELETE and PUT
app.listen(8080);

Another option is to change the version of express in your package.json to use Express 3 instead, ie.

"express": "~3.0.0"
