我已经在heroku 上部署了我的python 网站，但是当我访问该页面时，我看到了一条通用的heroku“应用程序错误”消息。然后当我进入终端并检查heroku日志时，我看到了：

2013-09-04T04:33:04.130527+00:00 heroku[web.1]: Starting process with command `python bin/app.py`

我不确定这意味着什么。此外，当我运行 foreman start 时，我收到以下消息，我不确定这是否相关：

21:43:00 web.1  | started with pid 1694
21:45:28 web.1  | 127.0.0.1:51458 - - [03/Sep/2013 21:45:28] "HTTP/1.1 GET /" - 404 Not Found

过程文件：

web: python bin/app.py

app.py：

import web

urls = ( '/hello', 'Index' )

app = web.application(urls, globals())
render = web.template.render('templates/')

class Index(object):
 def GET(self):
     return render.hello_form()
 def POST(self):
     form = web.input(name="Nobody", greet="Hello")
     greeting = "%s, %s" % (form.greet, form.name)
     return render.index(greeting = greeting)

if __name__ == "__main__":
 app.run()

Web.py 将端口分配为 8080。而 Heroku 分配了不同的端口。这可能是它没有绑定到 $PORT 的原因。您可以尝试将您的 Procfile 修改为

web: python bin/app.py ${PORT}

Heroku 将负责填充 PORT 值。
