我不确定我做错了什么，这个过程看起来非常简单：
我必须为django-visits模块修复一些东西，所以我分叉了这个：
https://bitbucket.org/jespino/django-visits
修复了吗。
然后在源文件夹中尝试执行：
python setup.py install
在我的mac os x上。首先它给出了一个错误：
Using /usr/local/lib/python2.7/site-packages

所以我做了：
sudo python setup.py install
我得到了这个输出：

看起来它有效，我在我的django应用程序上使用这个运行服务器，我收到此错误：

我查看了site-packages文件夹，确定.egg是一个文件而不是文件夹？然而在源代码中，构建和lib文件夹看起来是正确的。
所以我对python setup.py安装这么简单的命令感到困惑，这是怎么回事呢？
（我应该注意，我可以运行python setup.py构建）并将它创建的egg文件夹复制到site-packages文件夹。我得到了一个不同的错误，因为它并不认为代码存在（并且项目中不存在任何模型）。有人在评论中提到了迁移，但我不确定这有什么关系？我在我的项目中有一些未运行的迁移，但它们是我特意支持的，我不想运行（独立于此）
