我正在使用flask和http://flask.pocoo.org/docs/1.0/tutorial/factory/中的以下教程构建python Web应用程序。我正在从父目录运行烧瓶，但出现以下错误。
(venv) E:\python-code\python-web>flask run

请帮忙。
我已经尝试过Running Flask app from cli gives "no module named flaskr"
和
flask.cli.NoAppException: Failed to find application in module?
最佳答案
我发现了我的问题。我缺少return app作为代码中的最后一条语句。很抱歉造成您的困惑和歉意。
关于python - flask.cli.NoAppException:无法在模块“flaskr”中找到Flask应用程序或工厂。使用“FLASK_APP = flaskr:name”指定一个，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/55199434/
