Question

使用以下服务器代码：

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io');

//  Set the environment variables we need.
ipaddress = process.env.OPENSHIFT_NODEJS_IP;
port      = process.env.OPENSHIFT_INTERNAL_PORT || process.env.OPENSHIFT_NODEJS_PORT || 8080;

if (typeof ipaddress === "undefined") {
//  Log errors on OpenShift but continue w/ 127.0.0.1 - this
//  allows us to run/test the app locally.
console.warn('No OPENSHIFT_NODEJS_IP var, using 127.0.0.1');
ipaddress = "127.0.0.1";
};

app.get('/', function(req, res){
  res.sendfile('index.html');
});

http.listen(process.env.OPENSHIFT_NODEJS_PORT, process.env.OPENSHIFT_NODEJS_IP, function(){
console.log('listening on *:' + port + ", " + ipaddress);
});

我只是试图在我的代码中包含socket.io模块，甚至没有初始化io，并且我的代码在尝试在Openshift上启动应用程序时出错。当我删除＆＃34; var io = require（＆＃39; socket.io＆＃39;）;＆＃34;我的应用程序启动正常。

当我通过SSH进入我的服务器空间并查看node_modules时，看起来Openshift似乎没有安装socketio，即使我已将它包含在我的包中。

这是我的package.json：

{
  "name": "OpenShift-Sample-App",
  "version": "1.0.0",
  "description": "OpenShift Sample Application",
  "keywords": [
    "OpenShift",
    "Node.js",
    "application",
    "openshift"
  ],
  "author": {
    "name": "OpenShift",
    "email": "ramr@example.org",
    "url": "http://www.openshift.com/"
  },
  "homepage": "http://www.openshift.com/",
  "repository": {
    "type": "git",
    "url": "https://github.com/openshift/origin-server"
  },
  "engines": {
    "node": ">= 0.6.0",
    "npm": ">= 1.0.0"
  },
  "dependencies": {
    "express": "^4.10.2",
"socket.io": "^1.3.7"
  },
  "devDependencies": {},
  "bundleDependencies": [],
  "private": true,
  "main": "server.js"
}

在git push to Openshift期间，它表示包括socketio在内的所有软件包都安装正常。

我知道怎样才能让socketio模块在Openshift上正常运行？

Answer 1

由于插入字符

，看起来旧的npm版本在npm安装时出现问题

尝试在package.json

中替换下面的依赖项

"dependencies": {
  "express": "4.10.2",
  "socket.io": "1.3.7"
},

套接字IO在Openshift上不起作用
