django.db.utils.OperationalError：安装夹具时出现问题：没有这样的表：pages_page__old

如何解决django.db.utils.OperationalError：安装夹具时出现问题：没有这样的表：pages_page__old

当我尝试运行时：python3 manage.py createdb 添加密码后，在超级用户成功创建后出现错误。并且以下错误的结束是：

django.db.utils.OperationalError: Problem installing fixtures: no such table: pages_page__old

完整错误：

Traceback (most recent call last):
  File "/home/martaf/Travail_insPYration/shop/env/lib64/python3.9/site-packages/django/db/backends/utils.py",line 62,in execute
    return self.cursor.execute(sql)
  File "/home/martaf/Travail_insPYration/shop/env/lib64/python3.9/site-packages/django/db/backends/sqlite3/base.py",line 326,in execute
    return Database.Cursor.execute(self,query)
sqlite3.OperationalError: no such table: pages_page__old

The above exception was the direct cause of the following exception:
