    这是一个创建于 3529 天前的主题,其中的信息可能已经有所发展或是发生改变。
    我在使用Pycharm忘记使用virtualenv。
    污染了系统的Python环境,我想重置系统的Python环境。

    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
