在Elastic Beanstalk中部署flask应用程序时出错：无法识别选项绑定

Question

我有一个装在弹性豆茎上的烧瓶，它的结构是： （此文件夹结构也在Flask documentation中描述）

farmerselevator/
├╴.ebextensions/
│       └─── python.config
│
├─farmerselevator/
│  │  
│  ├─── database/
│  │
│  ├─── src/
│  │      ├ api/
│  │      ├ pages/
│  │      └ helper.py
│  │
│  ├─── static/
│  │
│  ├─── templates/
│  │
│  ├─── uploads/
│  │
│  └─── __init__.py
│
│
├╴farmerselevator.egg-info/
├╴requirements.txt
└╴setup.py

Mysetup.py包含：

from setuptools import setup

setup(
    name='farmerselevator',
    packages=['farmerselevator'],
    include_package_data=True,
    install_requires=[
        'flask',
    ],
)

而mypython.config

option_settings:
  "aws:elasticbeanstalk:container:python":
    WSGIPath: setup:setup

我的/farmerselevator/__init__.py有：

from flask import Flask
application = Flask(__name__)

# internal functions for api and pages calls
import farmerselevator.src.api.buy
...

import farmerselevator.src.pages.index
...

# running the server
if __name__ == '__main__':
    application.run()

要在本地运行我的应用程序，我运行：export FLASK_APP=__init__.py，后跟export FLASK_ENV=development和flask run

但是当我尝试在日志中部署到AWS Elastic Beanstalk时，我得到了一个错误：

问题：

我的python.config错误吗？我尝试将setup.py替换为application.py，并在python.config中进行匹配，但没有成功

错误是否与目录结构有关？在我以前的版本中，我有一个application.py，而不是在Flask doc中设计的文件夹结构，它在AWS中工作
