尝试在Rackspace中进行身份验证时出错

Question

我从Rackspace Documentation获得了以下代码。

import pyrax
pyrax.set_setting("identity_type", "rackspace")
pyrax.set_default_region('ORD')
pyrax.set_credentials('ot7336', '2755cd822321335191c8cc3ab46bbcff')

但是当我运行模块时，我收到以下错误消息

Traceback (most recent call last):
File "C:/Python27/rackspaceFileDownload.py", line 1, in <module>
import pyrax
ImportError: No module named pyrax

我已从此链接https://github.com/rackspace/pyrax/

下载了pyrax

解压缩并使用＆＃34; setup.py install＆＃34;

将其安装在CMD的Windows中
