python - 'utf- 8' can' t 解码位置 0 : invalid start byte 中的字节 0xc0

Question

我尝试执行 Django 的 createsuperuser 并收到以下错误。在syncdb数据库为空并以“utf-8”编码之前。我正在使用 pymysql。

D:\Python27\site\mysite>python manage.py syncdb
Creating tables ...
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_user_permissions
Creating table auth_user_groups
Creating table auth_user
Creating table auth_message
Creating table django_content_type
Creating table django_session
Creating table django_site

You just installed Django's auth system, which means you don't have any superuse
rs defined.
Would you like to create one now? (yes/no): yes

Answer 1

代码为C0的字节是invalid UTF-8 编码文本。我不知道该文本来自何处，但它要么是无效的 UTF-8，要么您的代码错误地尝试将其视为 UTF-8。
