啟動django項目時，報AttributeError: ‘str‘ object has no attribute ‘dcode‘

報錯提示：

 File "/home/lhz/.virtualenvs/python37_django/lib/python3.7/site-packages/django/db/backends/mysql/operations.py", line 146, in last_executed_query
    query = query.dcode(errors='replace')

解決方法：

點擊最後一個文件目錄，自動進入該文件中：/home/lhz/.virtualenvs/python37_django/lib/python3.7/site-packages/django/db/backends/mysql/operations.py

#將第165行中的decode修改成encode，
if query is not None:
query = query.decode(errors='replace')
return query
