python - 将 Python Flask App 部署到 Heroku R10 报错

Question

我希望使用免费的 dyno 将 flask 应用程序部署到 Heroku，它似乎构建成功:

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

在各种帮助站点中遇到此问题的所有其他人在绑定(bind)到 Heroku $PORT 时解决了他们的问题，与我的做法相同:

#!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)

还有我的Procfile:

web: python run.py runserver

难道我在运行虚拟环境？也许我的 83.2M 应用程序太大了？我有点被困在这里了。预先感谢您的帮助!

Answer 1

尝试像这样更改您的 Procfile 内容:

web: gunicorn run:app -b "0.0.0.0:$PORT"-w 3

run 是主应用程序文件的名称，表示 run.py
