在heroku上的socket.io + node.js
我在编译一个socket.io应用程序在heroku有一些问题。
那是app.js文件
var app = require('express').createServer() , io = require('socket.io').listen(app.listen(process.env.PORT || 5000)); app.get('/', function (req, res) { res.sendfile(__dirname + '/index.html'); }); var users = []; io.configure(function () { io.set("transports", ["xhr-polling"]); io.set("polling duration", 10); }); io.sockets.on('connection', function (socket) { socket.on('message',function(data,time,username){ socket.broadcast.emit('message',data,time,username); socket.emit('message',data,time,username,true); }); socket.on('connected',function(username){ socket.nick = username; users.push(username); io.sockets.emit('user_connected',users); }); socket.on('disconnect',function(){ users.splice(users.indexOf(socket.nick), 1); socket.broadcast.emit('updated_user_list',users); }); }); 的package.json
{ "name": "application-name", "version": "0.0.1", "private": true, "scripts": { "start": "node app" }, "engines": { "node": "0.8.x", "npm": "1.1.x" }, "dependencies": { "express": "3.0.0rc1", "jade": "*", "socket.io": "~0.9.8" } }
这是推向heroku时的错误

Heroku没有build立雇用。 原因是hiredis（node.js模块）依赖于需要GNU make的hiredis（C库），而这在你的slu not中是不可用的。
问题是，为什么NPM试图build立hiredis，而不是在你的依赖？
你应该检查hiredis是否出现在你项目的任何地方（ grep -R hiredis . ）。 另一种可能是Heroku试图提供redis到所有node.js应用程序？
我会检查Heroku的支持。
我正在遇到同样的问题，而与Heroku搞混了。 所有的path似乎都在那里。 运行Ubuntu 12.04，我甚至为gmake创build了一个sym链接。 没有什么解决它。 我最终尝试了这个
"dependencies": { "express": "3.0.0rc2", "ejs": "*", "stylus": "*", "mongojs": "0.4.3" }, "bundledDependencies": { "socket.io": "*" },
代替
"dependencies": { "express": "3.0.0rc2", "ejs": "*", "stylus": "*", "mongojs": "0.4.3", "socket.io": "*" },
这似乎解决了这个问题，使heroku快乐。 如果你find一个合适的解决scheme，请让我知道。
我已经发布了一个类似的问题在部署nodejs到heroku的答案，似乎已经解决了这个问题。
基本上尝试使用socket.io 0.9.6而不是0.9.8。
WAAAAAAAIT第二。
我注意到我运行grep -R hiredis . 在./node_modules/socket.io/node_modules目录下出现文件夹redis 。 显然， socket.io现在正在与内置的redis一起运行，与Heroku混淆。
尝试从socket.io的node_modules文件夹中删除redis文件夹。 我通过完全删除socket.io解决了这个问题。
当您在本地运行npm install ，hiredis会创build一些文件，其中包含特定于您机器的path。 当你将这些caching的依赖关系推送到Heroku时，构build失败。
Waf: Entering directory `/Users/gaggina/Desktop/socket2/node_modules/socket.io/node_modules/redis/node_modules/hiredis/build'
你可以通过从源代码控制中删除node_modules/hiredis目录来解决这个问题，让Heroku重新编译它：
git rm -rf node_modules/hiredis rm -rf node_modules/hiredis echo "node_modules/hiredis" >> .gitignore
我做了一些谷歌search，但无法find解决scheme，但我试图改变我的代码如下，它开始工作…
var express = require('express'), app = express(), server = require('http').createServer(app), io = require('socket.io').listen(server), var port = process.env.PORT || 5000; // Use the port that Heroku provides or default to 5000 server.listen(port, function() { }); io.configure(function () { io.set("transports", ["xhr-polling"]); io.set("polling duration", 10); io.set("log level", 1); });
让我知道如果你同样的问题，仍然没有成功..
