First Heroku deploy failed `error code=H10`
提问by ilyo
I deployed my app to Heroku. It's a node.js + express + socket.io app and this is the package.jsonfile
我将我的应用程序部署到 Heroku。这是一个 node.js + express + socket.io 应用程序，这是package.json文件
{
"name": "game_test",
"author": "Ilya",
"description": "A test app for our board game",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node app"
},
"dependencies": {
"express": "3.0.6",
"jade": "*",
"socket.io" : "*"
},
"engines": {
"node": "0.8.14"
}
}
This is the log I get:
这是我得到的日志：
heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=game-test-1.herokuapp.com fwd=37.26.146.185 dyno= queue= wait= connect= service= status=503 bytes=

What does it mean?
这是什么意思？

Found solution for me here: Heroku + node.js error (Web process failed to bind to $PORT within 60 seconds of launch)
在这里为我找到了解决方案：Heroku + node.js 错误（Web 进程无法在启动后 60 秒内绑定到 $PORT）
In my case my app crashed because I was hard setting the PORT, instead of using the port that heroku dinamicaly sets, which can be accessed with process.env.PORT
在我的情况下，我的应用程序崩溃了，因为我很难设置端口，而不是使用 heroku dinamicaly 设置的端口，可以通过访问 process.env.PORT
app.listen(process.env.PORT || 3000, function(){
console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env);
});

I just had a similar issue with my app, I got the issue after a migration of the DB, after trying many options, the one that helped me was this:
我的应用程序刚刚遇到了类似的问题，在迁移数据库后遇到了这个问题，在尝试了许多选项后，对我有帮助的是：
heroku restart
(Using Heroku toolbelt for mac)

In my case, i found same error because there is version difference of node and npm on my local machine and defined in package.json version.
就我而言，我发现了同样的错误，因为我的本地机器上存在 node 和 npm 的版本差异，并在 package.json 版本中定义。
"engines": {
"node": "0.8",
"npm": "1.2.x"
}
when i check using
当我检查使用
node --version : v0.10.41
npm --version : 1.4.29
when i update my package.json to
当我将 package.json 更新为
"engines": {
"node": "0.10.41",
"npm": "1.4.29"
}
It works fine :)
它工作正常:)

in my case adding process.env.PORT || 3000to my http server script, resolved.
My heroku log reported 'H20' error and 503 http status.
在我的情况下，添加process.env.PORT || 3000到我的 http 服务器脚本中，已解决。我的 heroku 日志报告了“H20”错误和 503 http 状态。

In my case, my Procfile was pointing to the wrong file (bot.js which I previously used) so once I updated it, the error was gone.
就我而言，我的 Procfile 指向错误的文件（我以前使用过的 bot.js），所以一旦我更新它，错误就消失了。

I faced this same problem and none of the answers above helped me. What i did was run:
我遇到了同样的问题，上面的答案都没有帮助我。我所做的是运行：
node --version
and in the package.json add the engines section with your node version:
并在 package.json 中使用您的节点版本添加引擎部分：
{
"name": "myapp",
"description": "a really cool app",
"version": "1.0.0",
"engines": {
"node": "6.11.1"
}
}

upon using hapi18, I find taking out the "host" field and setting the port to:
使用 hapi18 后，我发现取出“主机”字段并将端口设置为：
port: process.env.PORT || 5000did the trick.
port: process.env.PORT || 5000成功了。

Also check your database connection. I forgot to change my database connection from localhost and this crashed my app once it was pushed to heroku.
还要检查您的数据库连接。我忘记从 localhost 更改我的数据库连接，一旦它被推送到 heroku，我的应用程序就会崩溃。

In my own case, i got this error because i refuse to add a Procfile to my node js app and my "main": "app.js" was initially pointing to another js file as main. so doing these chnages get it fixed for me
在我自己的情况下，我收到此错误是因为我拒绝将 Procfile 添加到我的节点 js 应用程序中，而我的“main”：“app.js”最初指向另一个 js 文件作为主文件。所以做这些改变为我修复它
