如何重置 Ubuntu 14.04 的 Python 环境？

http://askubuntu.com/questions/505919/installing-anaconda-python-on-ubuntu

You can use wget to download from commandline:

wget http://09c8d0b2229f813c1b93-c95ac804525aac4b6dba79b00b39d1d3.r79.cf1.rackcdn.com/Anaconda-2.0.1-Linux-x86_64.sh

And after download is finished do:

bash Anaconda-2.0.1-Linux-x86_64.sh

@qinkun1234 文不对题
我不是需要安装anaconda，是要重置Ubuntu的Python环境，谢谢。

重装 python 试试。。好像没有直接能 reset 的

apt-get remove xx
apt-get install xx

@vivisidea
尝试了下似乎不是很靠谱，会 remove 掉一堆相关的东西，试试 --reinstall 看是不是想要的效果。。

xxx:$ sudo apt-get --reinstall install python

Anaconda是另一种换 py版本的方法:

$ conda create -n py3k python=3 ipython
...

$ source activate py3k
prepending /home/ilan/a150/envs/py3k/bin to PATH
(py3k)$ ipython
