Question

我希望使用免费的dyno将一个烧瓶应用程序部署到Heroku，它似乎成功构建：

remote: Git submodules detected, installing:
remote: 
remote: Compressing source files... done.
remote: Building source:
remote: 
remote: -----> Python app detected
remote: -----> Installing requirements with pip
remote: 
remote: -----> Discovering process types
remote:        Procfile declares types -> web
remote: 
remote: -----> Compressing...
remote:        Done: 83.2M
remote: -----> Launching...
remote:        Released v94
remote:        https://MYAPP.herokuapp.com/ deployed to Heroku
remote: 
remote: Verifying deploy... done.

然后在访问URL后检查Heroku日志我抛出了这个错误：

2017-10-25T22:33:09.264449+00:00 heroku[web.1]: Starting process with command `python run.py runserver`

2017-10-25T22:34:09.484569+00:00 heroku[web.1]: State changed from starting to crashed

在各种帮助网站中遇到此问题的所有其他人在绑定到Heroku $PORT时解决了他们的问题，与我的方法相同：

#!venv/bin/python
import os
from app import app
port = int(os.environ.get('PORT', 33507))
app.run(host='0.0.0.0', port=port, debug=False)

我的Procfile：

web: python run.py runserver

难道我正在运行虚拟环境吗？也许我在83.2M的应用程序太大了？我有点被困在这里。在此先感谢您的帮助！

Answer 1

尝试像这样更改您的Procfile内容：

网络：gunicorn run：app -b“ 0.0.0.0:$PORT” -w 3

其中run是主应用程序文件的名称，表示run.py

Answer 2

尝试更改：

Procfile内容应为：
```
web: python run.py
```
端口号从33507到8080
debug = True。
