Question

运行服务器时出现以下错误。我使用Django === 1.10.2和默认的sqlite3数据库作为后端。但我有以下例外：

python manage.py runserver
Performing system checks...

    raise MigrationSchemaMissing("Unable to create the django_migrations table (%s)" % exc)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf1 in position 6: ordinal not in range(128)

任何解决方案都可以理解????

Answer 1

似乎你在某处设置了一个奇怪的角色，很可能是在django设置中指定的sqlite文件的名称。

Django试图做raise MigrationSchemaMissing("Unable to create the django_migrations table (%s)" % exc) - 当这样做时遇到UNICODE错误，该错误告诉0xf1不是ASCII的一部分。根据{{3}}，这是字符±。由于django绝对不会将其用作表名，我猜它必须与文件名相关。

如果不是这种情况，请尝试项目文件夹中的grep '±' .以查找此字符的用法。 HTH

我正面临着启动runserver django？
