Introduction

The author, known as "皮皮", shares a question from the Python community about an sqlalchemy error that many encountered.

Problem Description

Solution

After consulting GPT and reviewing the error, the author confirmed that the problem was indeed the version change. The fix is to either downgrade back to sqlalchemy==1.4.42 or adjust the code to be compatible with version 2.x, removing the now‑obsolete encoding argument.
