I just started learning flask and I am stuck at setting up Flask. I don't know how to setup environment variable. Whenever I use the Flask run command, I encounter the following. I did a lot of google searches to setup environment variable on Windows but I am unable to find and somemtime not able to understand the solution. How to do this ? How to get the "app.py" or "wsgi.py" ? Please help.

命令:烧瓶运行

错误消息:无法找到Flask应用程序.您未提供"FLASK_APP"环境变量，并且在当前目录中找不到"wsgi.py"或"app.py"模块.

Error message : Could not locate a Flask application. You did not provide the "FLASK_APP" environment variable, and a "wsgi.py" or "app.py" module was not found in the current directory.

错误消息

推荐答案

您需要提供一个应用程序环境.因此Flask需要知道.py文件才能运行. 尝试运行该命令

you need to provide an application environment. So Flask needs to know, the .py file to run. Try to run that command

export FLASK_APP=application.py

其中application.py-在我的情况下，Flask应用程序的名称是application.py.

where application.py - name of your Flask app in my case it is application.py.

之后

flask run
