解决Win7(x64)Anaconda3报错：AttributeError: '_NamespacePath' object has no attribute 'sort'

最近论文需要用到python做数据分析，python语法简单，但是Windows下安装第三方包恶心的要命，statsmodels用pip死活安装不上，网上查了说包相互依赖windows下的pip不能下载全，还有好几个其他的统计包也是如此，整晕了算。

看网上有些python大牛推荐Anaconda，可以解决包的问题，于是卸载本地的python，从官网上下了个Anconda玩玩，结果遇到新问题。

问题如下：

经过一番查找，解决方法如下：

问题解决原链接(英文)：https://github.com/conda/conda/pull/5496

找到你的Anaconda安装目录中的path.py，详细路径为：D:\ProgramData\Anaconda3\Lib\site-packages\conda\_vendor\auxlib\path.py

把文件path.py中，“except ImportError: ”修改为“except Exception:“

在运行Anaconda Prompt，输入conda，效果图如下：

这里问题还没有彻底解决，在PyCharm这种编译器指向Python的时候，还是会出问题，问题如下：

这时候需要更新Pip，打开Anaconda Prompt，输入命令conda update conda pip，联网更新pip

在打开pycharm，右下角会更新一些python信息

然后还没有完，更新完了跑，还是出问题，问题如下：

最后一气之下，找到D:\ProgramData\Anaconda3\lib\site-packages\setuptools-27.2.0-py3.6.egg，然后删除（不放心的话，剪切到别的地方）

然后运行，好了。。。。

希望对踩坑的朋友有帮助。
