我的 Django 应用有问题，我删除了我的产品应用以进行更多练习，当我使用 migrate 或 makemigrations 代码时，我收到此错误：

NameError: name 'o' is not defined

我不知道这是什么，我没有更改 os 或其他任何内容。我将不胜感激。

【问题讨论】：

检查您的 urls.py 文件，第 15 行。您可能错误地输入了“o”。
请将您的urls.py 添加到问题中，以便我们查看可能出现的问题。

标签： python django nameerror

【解决方案1】：

您在 urls.py 第 15 行输入了“o”，只需删除并保存文件并删除迁移文件并再次迁移所有详细信息
