Python 属性错误：'；RegexURLPattern'；对象没有属性'_回调&x27；

我是python的新手。我使用了本教程，但对RegexURLPattern有一个问题。 问题的完整堆栈跟踪：

我做错了什么？请提供帮助…

看起来您的项目布局与快速启动不同

from quickstart import views

应该是：

from tutorial.quickstart import views

---

您正在使用Django的开发版本。DRF尚未兼容。您应该安装Django 1.8.x或1.9.x

在我的例子中，似乎没有安装DRF。我运行了pip安装djangorestframework，我的“runserver”命令运行得很好。

我在Django 1.10和1.11上也有同样的问题。 解决方案：将djangorestframework更新至最新版本

pip install -U djangorestframework

---

那是疯狂的虫子。我浪费了两天的周末才意识到它必须安装特定的版本：

• Django 1.11（我的上一个版本是1.11.3）
• djangorestframework 3.7
• python 3.6.5

祝你们好运

如果我像您所说的那样编辑这一行，我会遇到另一个错误：导入错误：没有名为“tutorial.quickstart”的模块正如我所说，您的快速启动布局与文档不同。请确保在创建快速启动应用程序时您在tutorial目录中。/Users/user/tutorial/tutorial/quickstart请显示完整的回溯。您使用的是哪个Django和DRF版本？更新的堆栈跟踪…Django版本-1.10 DRF-我不知道。我用pip安装djangorestframework安装它只是为了参考：从restframework3.4.0开始，Django 1.10就受支持。

pip install -U djangorestframework
