just started on using web.py and heroku, so...

I have this simple app that I want to upload to heroku and I have followed the instruction from http://joshuaoiknine.com/post/47196802362/publishing-for-the-web-py-python-framework-to-heroku

This is my Procfile:

web: python code.py $PATH

But after I uploaded it to heroku, it gives me the application error. The heroku log shows me this:

2013-08-08T03:27:44.956675+00:00 heroku[web.1]: Starting process with command `python code.py /usr/local/bin:/usr/bin:/bin`

2013-08-08T03:27:46.881655+00:00 heroku[web.1]: State changed from starting to crashed

However, when i tried the second method, I receive this error:

Traceback (most recent call last):
  File "code.py", line 55, in <module>
    app.run(host='0.0.0.0', port=port)
TypeError: run() got an unexpected keyword argument 'host'

Any ideas how to get my app onto heroku up and running?

code.py首先需要一个整数参数，而不是你的 $PATH。它可能是它所期望的端口，因此而不是$PATH在您的Procfilepass$PORT中。

更好的是：更改要使用的代码ENV["PORT"]，如果未定义（在您的本地开发环境中可能是这种情况），则使用默认值（例如，您的开发环境为 8000 或 8080）。

在 Heroku 上，您的服务器需要监听的端口不是固定的——它会随着每次 dyno 的每次重启而改变。Heroku 会设置环境变量PORT，让你知道监听哪个端口。
