Flask App通过Heroku部署时由于Error = H10而导致应用程序错误
[英]Flask App results in Application Error when deployed through Heroku due to Error=H10
问题描述
I am attempting to deploy a simple Flask app through Heroku, yet I am receiving an H10 Error. 
我试图通过Heroku部署一个简单的Flask应用程序，但是却收到H10错误。 I am manually deploying with Github on the Heroku website. 我正在Heroku网站上与Github一起手动部署。
I have tried using to commands 'heroku restart', heroku ps:scale web=1, pip freeze > requirements.txt, and dynos and changing my Procfile to include -b :$PORT, changing the PORT in my flask python file to app.run(debug=True, port=33507, port = int(os.environ.get('PORT', 5000)) and app.run(host='0.0.0.0', port=port), changing my repo to match https://github.com/zachwill/flask_heroku , and adding gunicorn and gevent to the requirements.txt. 我已经尝试过使用命令'heroku restart'，heroku ps：scale web = 1，pip Frozen> requirements.txt，和dynos并将我的Procfile更改为包括-b：$ PORT，将我的flask python文件中的PORT更改为app .run（debug = True，port = 33507，port = int（os.environ.get（'PORT'，5000））和app.run（host ='0.0.0.0'，port = port），将我的仓库更改为匹配https://github.com/zachwill/flask_heroku ，然后将gunicorn和gevent添加到requirements.txt。
App 应用程式
port = int(os.environ.get('PORT', 5000))
if __name__ == '__main__':
app.run(host='0.0.0.0', port=port)
Procfile 程序文件
web: gunicorn -b :$PORT flaskapp:app
requirements.txt requirements.txt
gunicorn
gevent

The app is 'deploying', but something is wrong with the server end. 该应用程序正在“部署”，但是服务器端出了点问题。 Making a runtime.txt with my current python version stops the app from deploying. 使用我当前的python版本制作runtime.txt会阻止应用程序部署。 Should I make this a different version, then? 那我应该把它改成其他版本吗？ I'm a newbie, so my deep apologies if I am making just a simple error. 我是新手，所以如果我犯了一个简单的错误，我深表歉意。

The requirements.txt did not include flask_wtf, bs4, requests, or app, all of which were imported in my flaskapp.py file. requirements.txt不包括flask_wtf，bs4，请求或应用程序，所有这些都已导入我的flaskapp.py文件中。 This file only included gunicorn and gevent previously. 此文件以前仅包括gunicorn和gevent。
