python - 烧瓶运行没有运行并给我错误

Question

我试图运行烧瓶，当我运行烧瓶时

我收到这个错误

(snoop) ether@ether:~/Documents/loginsystem$ flask run
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]

Error: 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.

我已经做好了

Run command: set FLASK_APP=main.py
Run command: set FLASK_DEBUG=1
Run command: flask run

但这不会改变错误的任何内容

我将本教程用于登录系统 https://codeshack.io/login-system-python-flask-mysql/

Answer 1

您可以尝试导出变量而不是仅设置它吗？

export FLASK_APP=main.py

并不是

set FLASK_APP=main.py
