在運(yùn)行命令：
python wsgi.py
報(bào)錯(cuò)：

AttributeError: can't set attribute
run 在wsgi.py文件中app = create_app()時(shí)，找init.py中create_app():執(zhí)行到dbchemy.create_all()或者是db.create_all()時(shí)铃肯，AttributeError: can't set attribute
參考文章的評(píng)論：https://discuss.helloflask.com/t/topic/662
知道了解決辦法
pip install -U flask-sqlalchemy
我當(dāng)前的 flask-sqlalchemy=2.4.4，看了文章說是庫(kù)的問題朴皆，已修復(fù)這個(gè)問題，目前包含這個(gè)修復(fù)的2.5.0版本已發(fā)布泛粹，更新后運(yùn)行成功。
