flask shell 执行db.create_all()产生错误 AttributeError: can’t set attribute

本文主要是介绍flask shell 执行db.create_all()产生错误 AttributeError: can’t set attribute,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

在运行命令:
python wsgi.py
报错:

Traceback (most recent call last):
  File "wsgi.py", line 5, in <module>
    app = create_app()
  File "C:\Users\kegek\Desktop\flask_tencent\flaskr\__init__.py", line 52, in create_app
    dbchemy.create_all()

    sa_url.database = os.path.join(app.root_path, sa_url.database)
AttributeError: can't set attribute

run 在wsgi.py文件中app = create_app()时,找init.py中create_app():执行到dbchemy.create_all()或者是db.create_all()时,AttributeError: can't set attribute

参考文章的评论:https://discuss.helloflask.com/t/topic/662
知道了解决办法
pip install -U flask-sqlalchemy
我当前的 flask-sqlalchemy=2.4.4,看了文章说是库的问题,已修复这个问题,目前包含这个修复的2.5.0版本已发布,更新后运行成功。
