python之运行 *requests* 时出错

使用此处的说明在 OSX 10.10 上安装了 Python/Pip http://docs.python-guide.org/en/latest/starting/install/osx/

只有安装才能访问 Pip

使用pip install requests安装的请求

运行脚本

import requests 
 
feed_url = 'http://www.mylocation.com/the_data' 
 
#grab xml from URL 
r = requests.get(feed_url) 
r.text 
 
print r 

错误是

otool -L $(which python) 的输出
