环境：python3.7+django2.2
报错信息：
AttributeError: ‘str’ object has no attribute ‘decode’
解决办法：
找到python文件下的django文件>db文件>backends>mysql>operations.py
打开文件：
打开后ctrl+f搜索query.decode
然后将query.decode改为query.encode
#原代码：
query = getattr(cursor, '_executed', None)
if query is not None:
query = query.decode(errors='replace')
return query
#修改为：
query = getattr(cursor, '_executed', None)
if query is not None:
query = query.encode(errors='replace')
return query
然后就好了，问题解决！
