我正在关注有关如何从here首次向Django提供补丁的教程。在为django的测试套件安装依赖项时遇到错误。到目前为止，我已经遵循了文档中提到的所有内容。当我执行此命令时：
(djangodev) apoorv@apoorv:~/django_dev_copy/django/tests$ pip install -r requirements/py3.txt
安装过程中途出现错误：

我不知道为什么会这样。在教程中，它说：“如果在安装过程中遇到错误，则您的系统可能缺少对一个或多个Python软件包的依赖性。请查阅失败软件包的文档或在网络上搜索遇到的错误消息。”
我在这里想念什么？我正在使用Ubuntu 18.04。 Anaconda Python 3.6.5。
