Python heroku错误H20应用启动超时，R10启动超时 [英] Python heroku error H20 App boot timeout, R10 boot timeout

问题描述

我以示例为例: http://flask.pocoo.org/docs/quickstart/，并且可以在"foreman start"之后在自己的机器上很好地运行它，但是当我在heroku上部署它时，出现R10超时错误.

I do as the examples: http://flask.pocoo.org/docs/quickstart/, and I can run it well on my own machine after "foreman start", however when I deploy it on heroku, I got R10 timeout error.

我写了Procfileas:

I wrote the Procfileas :

web: python flaskr.py

并且为了运行"git push heroku master"命令，我删除了"disreibute == 0.6.24"这句话，因为如果没有，我将得到如下错误:

and in order to run the "git push heroku master" command, I delete the "disreibute==0.6.24" sentence because if not, I would get an error as follows:

Traceback (most recent call last):
File "<string>", line 1, in <module>
NameError: name 'install' is not defined

所以我不知道这是Procfile还是requirements.txt文件是错误的还是其他错误.我几乎阅读了所有找到的文章，但问题尚未解决.

So I don't know whether it is the Procfile or the requirements.txt file is wrong or something else is wrong. I almost read all articles I have found but the problem is not solved yet.

此外，该示例使用了SQLite3数据库，我不知道它是否与此有关.

Besides, the example used SQLite3 database, I don't know whether it has something to do with this..

最后，我将在此处列出日志:

In the last, I will list the logs here:

我注意到slug编译可以正常完成，然后出现R10错误.

I noticed that slug compilation can finish normally and then R10 error follows.

推荐答案

针对我们的node.js应用程序的以下解决方案可能会帮助到这里结束的任何人.

The following solution for our node.js app might help anyone who ends up here.

听127.0.0.1会导致我们遇到 code = H20 desc =应用启动超时" 问题.将收听地址更改为0.0.0.0 即可解决问题.

Listening to 127.0.0.1 leads to the code=H20 desc="App boot timeout" problem for us. Changing the listening address to 0.0.0.0 solves the problem.

此外，不要使用您自己的端口，而是使用环境变量PORT ，该变量由heroku传递给您的应用环境变量.否则，您也会遇到此问题.

Also, don't use your own port, but instead use the environment variable PORT , which is passed to your app environment variables by heroku. Otherwise, you'll also get this problem.

这是我们的节点代码:

const { PORT=3000, LOCAL_ADDRESS='0.0.0.0' } = process.env
server.listen(PORT, LOCAL_ADDRESS, () => {
  const address = server.address();
  console.log('server listening at', address);
});

因此，请尝试记录您的监听地址和端口并首先进行检查.

So, try to log your listening address and port and check them firstly.
