TypeError: 'float' object is not callable #189

Closed Ninniachwen closed 2 years ago

Ninniachwen commented 2 years ago

after solving several other errors, I came across this rather generic one and I am at a loss on how to solve it. I upgraded the SQLAchemy version to 1.4, to avoid AttributeError: module 'time' has no attribute 'clock' then downgraded a bit again 1.3.24, to avoid the error can't set Variable.

so my recent setup is slightly different from the original SQLAlchemy==1.3.24 cffi>=1.11.5 Pillow>=5.3.0

also, I changed the config line into SQLALCHEMY_DATABASE_URI = 'sqlite:///site.db' to avoid AttributeError: 'NoneType' object has no attribute 'drivername'

However, when I start the app I now get TypeError: 'float' object is not callable
