追踪源码：
问题文件：Python36\lib\site-packages\django\db\backends\mysql\base.py
def get_new_connection(self, conn_params):
conn = Database.connect(**conn_params)
conn.encoders[SafeText] = conn.encoders[six.text_type]
conn.encoders[SafeBytes] = conn.encoders[bytes]
return conn
解决方案
- 给MySQLclient降级。先卸载，再安装指定版本。
pip3 uninstall mysqlclient，pip3 install mysqlclient==1.3。 - 我最开始的解决方案，改django的代码(Python36\lib\site-packages\django \db\backends\mysql\base.py)，加一个if：
def get_new_connection(self, conn_params):
conn = Database.connect(**conn_params)
conn.encoders[SafeText] = conn.encoders[six.text_type]
# 先判断bytes是否存在于编码器中，如果在才执行操作
if bytes in conn.encoders:
conn.encoders[SafeBytes] = conn.encoders[bytes]
return conn
