瓶flask.cli.no异常使用app factory

Question

我试图将我的配置设置拆分为配置.py文件，here

我将我的项目分成如下文件夹：

/bloggy
    autoapp.py
    config.py
    /app
        __init__.py
        models.py
        views.py
        /static
        /templates

我的config.py如下所示

^{pr2}$

我有一个应用程序工厂文件autoapp.py，从所需的环境变量创建我的Flask应用程序

import os
from app import create_app
app = create_app(os.getenv('FLASK_CONFIG') or 'default')

我的app/__init__.py如下所示：

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from config import config

db = SQLAlchemy()


def create_app(config_name):
    app = Flask(__name__)
    app.config.from_object(config[config_name])
    db.init_app(app)
    return app

运行后

$ export FLASK_APP=autoapp.py

以及

$ export FLASK_DEBUG=1

启动服务器时：

$ flask run

我得到以下错误：

Traceback (most recent call last):
  File "/home/jwe/.local/lib/python3.5/site-packages/flask/cli.py", line 178, in __call__
    self._flush_bg_loading_exception()

    'is .py' % module)
flask.cli.NoAppException: The file/path provided (autoapp) does not appear to exist.  Please verify the path is correct.  If app is not on PYTHONPATH, ensure the extension is .py

我是否可以让我的应用程序使用config.py中的设置，或者我应该采取不同的方法？在

也许添加flask应用程序的名称会有所帮助。如下所示：

app.config.from_object(bloggy.config[config_name])
