运行python程序时，遇到了问题：

ImportError: No module named sklearn.cluster

本以为就简单的安装个包就可以，执行如下：

pip install scikit-learn

结果却出错：

根据[https://blog.csdn.net/aiqinchao/article/details/89522180][https_blog.csdn.net_aiqinchao_article_details_89522180]的提示换了国内源也不行

此时有点懵逼，从来没出现过这个问题，遂尝试用apt-get安装：

sudo apt-get install python-sklearn

结果也报错，提示apt-get升级一下，我又执行 sudo apt-get update，结果还是不行：

就在无可奈何的时候找到一篇博客[https://blog.csdn.net/aiqinchao/article/details/89522180][https_blog.csdn.net_aiqinchao_article_details_89522180]，说是DNS出现了问题，我没有动过网络DNS怎么会有问题，本着死马当活马医的态度，修改了DNS，结果令我惊喜，一切又恢复了原样，pip install xxx，apt-get update 统统ok，在这谢谢博主，以下是修改方法：

1. 打开’/etc/network/interfaces’文件，没有则创建一个，添加

dns-nameservers  223.5.5.5   223.6.6.6

2. 打开’/etc/resolv.conf’文件并添加两行’

nameserver  223..5.5.5 
    nameserver  223.6.6.6
