AttributeError: 'str' object has no attribute 'decode'

执行

python3 manage.py makemigrations

报错如下

packages/Django-2.2-py3.7.egg/django/db/backends/mysql/features.py", line 82, in is_sql_auto_is_null_enabled
    cursor.execute('SELECT @@SQL_AUTO_IS_NULL')
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/Django-2.2-py3.7.egg/django/db/backends/utils.py", line 103, in execute
    sql = self.db.ops.last_executed_query(self.cursor, sql, params)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/Django-2.2-py3.7.egg/django/db/backends/mysql/operations.py", line 146, in last_executed_query
    query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

 

解决方法如下（注意替换自己的django的位置）

1.

cd /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/Django-2.2-py3.7.egg/django/db/backends/mysql

2

vim operations.py

 

3

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

解决方法：把decode改为encode即可。

 

4保存并退出。
