问题描述
我在 heroku 上编译 socket.io 应用程序时遇到了一些问题.
I'm having some issues in compiling a socket.io app on heroku.
这就是 app.js 文件
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
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"
}
}
这是推送到heroku时的错误
And that's the error when pushing it to heroku

推荐答案
Heroku 无法构建hiredis.原因是hiredis(node.js 模块)依赖于hiredis(C 库)，它需要GNU make，而你的slug 上没有.
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.
问题是，为什么 NPM 尝试构建hiredis 而它不在您的依赖项中?
Question is, why is NPM trying to build hiredis while it's not in your dependencies ?
您应该检查hiredis 是否出现在您项目中的任何位置(grep -Rhiredis .).另一种可能性是 Heroku 试图为所有 node.js 应用程序提供 redis ?
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 ?
我会与 Heroku 的支持人员核实.
I'd check with Heroku's support.
