安装python模块的问题
嗨，我无法下载python模块dm.smlsec.binding 1.0b3。 我得到以下错误。 我附上了我的日志文件，请帮我整理一下
/ usr / local / bin / pip on Thu Jul 18 12:23:36 2013下载/解压缩dm.xmlsec.binding
对包dm.xmlsec.binding运行setup.py egg_info

使用pip
安装Python包管理器： python-pip 
。
安装最新的稳定版本运行
sudo pip install dm.xmlsec.binding
或者如果您需要特定版本：
sudo pip install dm.xmlsec.binding==1.0b3
使用pip这个方法优于easy_install或setup.py ，因为它可以跟踪依赖关系和更新，就像在Ubuntu上的apt一样。
