如何在Windows上为“烧瓶运行"设置环境变量? [英] How to setup environment variables for `flask run` on Windows?

问题描述

我刚刚开始学习Flask，但是我一直在设置Flask环境变量.我不知道如何设置环境变量.每当我使用 flask run 命令时，都会遇到以下错误:

I just started learning flask and I am stuck at setting up the Flask environment variables. I don't know how to setup the environment variables. Whenever I use the flask run command, I encounter the following error:

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

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.

我做了很多Google搜索来在Windows上设置环境变量，但是我找不到解决方案，有时我无法理解该解决方案.

I did a lot of google searches to setup environment variables on Windows but I am unable to find a solution and sometimes I am not able to understand the solution.

如何执行此操作?如何获取"app.py"或"wsgi.py"?

How to do this ? How to get the "app.py" or "wsgi.py" ?

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 -您的Flask应用的名称是application.py.

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

之后

flask run
