我想学习flask,并为此创建了一个小程序。当我尝试运行它时,我得到了以下错误。flask run
错误-
* 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.
如果我尝试将文件名改为 app.py
顺利运行,但当文件名为 flaskblog.py
它不工作。
我试着按照blog->中的建议设置环境变量。如何在PyCharm中设置环境变量? 中的建议设置环境变量,但没有任何效果。
附上截图。环境变量文件的内容
我能够通过在终端上设置环境变量来解决这个问题。set FLASK_APP=flaskblog.py
然后它就像顺利地运行了。
