【问题描述】：
在使用 requirements.txt 与直接使用 pip 安装时，我看到了一些奇怪的行为。希望您能对此有所了解。
这可能与这个未回答的问题相同：pip install -r requirements.txt fails on scipy, but works when run manually line-by-line
Python 2.7.6
Django 1.6.11
当我像这样使用 requirements.txt 安装 mailchimp3 时：
sudo /usr/local/python/django/bin/pip install -r config/myvr/requirements.txt
安装失败，我看到了：

但是，当我像这样直接安装时：
sudo /usr/local/python/django/bin/pip install mailchimp3==2.0.3
安装成功：

这必须使用需求文件安装，而不是直接为我们的生产环境安装。你有没有可能知道这里有什么？
您还需要其他信息吗？

您可以发布您的 requirements.txt 文件以及您使用的 pip 版本吗？
