[Django] query = query.decode(errors=‘replace‘) AttributeError: ‘str‘ object has no attribute ‘de

Django runserver的时候遇到这个问题：

........
     res = instance.__dict__[self.name] = self.func(instance)
  File "E:java_pythonwork_codetmpatp-masterenv_atplibsite-packagesdjangodbbackendsmysqlfeatures.py", li
ne 82, in is_sql_auto_is_null_enabled
    cursor.execute('SELECT @@SQL_AUTO_IS_NULL')
  File "E:java_pythonwork_codetmpatp-masterenv_atplibsite-packagesdjangodbbackendsutils.py", line 103, i
n execute
    sql = self.db.ops.last_executed_query(self.cursor, sql, params)
  File "E:java_pythonwork_codetmpatp-masterenv_atplibsite-packagesdjangodbbackendsmysqloperations.py",
line 146, in last_executed_query
    query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

重点日志：

   query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

我用的是虚环境，去虚环境下找到这个文件，修改下这里的配置；
解决办法：
将这个路径下的E:java_pythonwork_codetmpatp-masterenv_atplibsite-packagesdjangodbbackendsmysqloperations.py

query = query.decode(errors='replace')
替换成：
query = errors='replace'

重新运行下命令就ok了
