在heroku上的socket.io + node.js [英] socket.io + node.js on heroku
本文介绍了在heroku上的socket.io + node.js的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这就是app.js文件
$ b 我在编译一个socket.io应用程序时遇到了一些问题。 $ b
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 = [];
$ b $ 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（用户名）;
io.sockets.emit（'user_connected'，users）;
}）;
socket.on（' disconnect（）函数（）{
users.splice（users.indexOf（socket.nick），1）;
socket.broadcast.emit（'updated_user_list'，users ）;
}）;
}）;
package.json
{

version：0.0.1，
private：true，
脚本：{

}
这就是将它推到heroku时的错误

解决方案
Heroku未能创建hiredis。原因是hiredis（node.js模块）依赖于hiredis（C库），它需要GNU make，这在你的slu not上不可用。
问题是，为什么NPM试图建立hiredis，而它不在你的依赖关系？
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试图为所有node.js应用程序提供redis？
我会检查Heroku的支持。
I'm having some issues in compiling a socket.io app on heroku.
Thats the app.js file
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);
});
});
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"
}
}
And that's the error when pushing it to heroku

解决方案
Heroku is failing to build hiredis. The reason is that hiredis (the node.js module) depends on hiredis (the C library), which needs GNU make, which is not available on your slug.
Question is, why is NPM trying to build hiredis while it's not in your dependencies ?
You should check if hiredis appears anywhere in your project (grep -R hiredis .). Another possibility is that Heroku is trying to provide redis to all node.js apps ?
I'd check with Heroku's support.
