毕设web项目启动时，报错

  File "D:\Program Files (x86)\Python\lib\site-packages\django\db\backends\mysql\operations.py", line 146, in last_executed_query
    query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

找到错误代码（line146）：query = query.encode(errors=’replace’)

解决方法：把decode改为encode即可。
