我在 Heroku 上编译 socket.io 应用程序时遇到了一些问题。

那就是 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);
  });

});

包.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"
  }
}

这就是将它推到heroku时的错误

Heroku 未能构建hiredis。原因是hiredis（node.js 模块）依赖于hiredis（C 库），它需要GNU make，这在你的slug 上不可用。

问题是，为什么 NPM 尝试构建不在您的依赖项中的hiredis？

您应该检查hiredis 是否出现在您的项目中的任何位置（grep -R hiredis .）。另一种可能性是 Heroku 正在尝试为所有 node.js 应用程序提供 redis ？

我会检查 Heroku 的支持。

WAAAAAAAIT 一秒钟。

在我运行之后我注意到在grep -R hiredis .目录下./node_modules/socket.io/node_modules出现了文件夹redis。显然，socket.io现在是redis内置的，这与 Heroku 混淆了。

尝试redis从socket.io's文件夹中删除文件node_modules夹。我通过完全删除 socket.io 解决了这个问题。

我在搞乱heroku时遇到了同样的问题。所有的路径似乎都在那里。运行 Ubuntu 12.04，我什至为 gmake 创建了一个符号链接。没有什么能解决它。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": "*"
},

这似乎解决了它并使heroku高兴。如果您找到合适的解决方案，请告诉我。

当您在npm install本地运行时，hiredis 会创建一些具有特定于您机器的路径的文件。当您将这些缓存的依赖项推送到 Heroku 时，构建会失败。

Waf: Entering directory `/Users/gaggina/Desktop/socket2/node_modules/socket.io/node_modules/redis/node_modules/hiredis/build'

你可以通过node_modules/hiredis从源代码管理中删除目录，让 Heroku 重新编译它来解决这个问题：

git rm -rf node_modules/hiredis
rm -rf node_modules/hiredis
echo "node_modules/hiredis" >> .gitignore

我已经在将 nodejs 部署到 heroku时发布了一个类似问题的答案，这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。

我做了一些谷歌搜索，但找不到解决方案，但我尝试如下更改我的代码，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);
});

让我知道你是否同样​​的问题，但仍然没有成功..
