Database 如何处理这个错误(1049，未知数据库'usersohyunjunworkastralmysql')

在Django settings.py中，我这样设置数据库选项

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': os.path.join(BASE_DIR, 'mysql'),
        'USER': 'root',
        'PASSWORD': 'sp153426',
        'HOST': '127.0.0.1',
        'PORT': '3306',
    }
}

我执行了这个命令

Python manage.py syncdb

但由于这个错误而失败了
