分析了原因后，以为权限不够，所以就把这个目录：
/Users/rocky/Library/Caches/pip/
做了提权： sudo /Users/rocky/Library/Caches/pip/
然后重新运行sudo pip install matplotlib
然后没有上面提示的错误。 然后在主程序中继续运行，结果还是出现：matplotlib模块没找到。
 
删除后重装，问题依然存在。
 
于是尝试用easy_install 安装， sudo easy_install matplotlib
 
等待了大概10多分钟，居然安装成功了。 因为下载的服务器比较慢，所以等待的时间就有点长了。
