django - 我正面临启动 runserver django？

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。但我有以下异常(exception):

python manage.py runserver
Performing system checks...
System check identified no issues (0 silenced).

    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赞赏？？？？

您似乎在某处设置了一个奇怪的字符，很可能是在 django 设置中指定的 sqlite 文件的名称中。

Django 在尝试做时死了 raise MigrationSchemaMissing("Unable to create the django_migrations table (%s)" % exc) - 执行此操作时遇到 UNICODE 错误，该错误表明 0xf1 不是 ASCII 的一部分。基于 this table这是字符± .由于 django 绝对不会使用它作为表名，我想它必须与文件名有关。

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