Python 2.7 安装python xbrl 1.0.7时出错

我遇到了在python上安装xbrl模块的问题，它困扰了我两天，我还没有解决它。我成功地安装了pip。我在安装lxml时遇到了同样的问题

当我使用：$sudo pip install python xbrl时，我得到了

Downloading/unpacking python-xbrl
  Downloading python-xbrl-1.0.7.tar.gz

我假设它已成功安装，但是，当我导入xbrl时，它不起作用

$python

>>> import xbrl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named xbrl

在安装大多数模块时，我总是遇到同样的问题。经过30个小时的努力，我已经绝望了。所以请帮帮我。谢谢

那是因为包裹坏了：
