Question

我是一个python / django noob，在尝试学习时无法运行我的代码。请告诉我如何解决以下我遇到的错误，谢谢。

在我的新项目的根文件夹中，我在命令行输入以下内容，这就是：

python manage.py runserver

验证模型......

>/Users/MyClean/anaconda/lib/python2.7/site-packages/django/utils/hashcompat.py:9: DeprecationWarning: django.utils.hashcompat is deprecated; use hashlib instead

我查看了我的项目代码（这是非常基本的）并且没有看到任何拼写错误。我正在从一本3岁的书中复制，所以我认为这是一个兼容性问题。

我正在复制一本3岁的书，所以我认为这是一本书兼容性问题。

3年是很长的一段时间。

在django 1.4中，verify_exists选项已被弃用（这意味着它被标记为删除），而在1.5中它被完全删除。

由于1.5是当前版本，因此当您安装django时，这是已安装的版本。

当你走过一本书时，尝试使用相同版本的django作为书。否则你会遇到更多这些问题。

或者，使用更新的参考。为什么不试试official tutorial？

如何在Django中修复这些错误？
