解決Win7(x64)Anaconda3報錯：AttributeError: '_NamespacePath' object has no attribute 'sort'

最近論文須要用到python作數據分析，python語法簡單，可是Windows下安裝第三方包噁心的要命，statsmodels用pip死活安裝不上，網上查了說包相互依賴windows下的pip不能下載全，還有好幾個其餘的統計包也是如此，整暈了算。

看網上有些python大牛推薦Anaconda，能夠解決包的問題，因而卸載本地的python，從官網上下了個Anconda玩玩，結果遇到新問題。

問題以下：

通過一番查找，解決方法以下：

問題解決原連接(英文)：https://github.com/conda/conda/pull/5496

找到你的Anaconda安裝目錄中的path.py，詳細路徑爲：D:\ProgramData\Anaconda3\Lib\site-packages\conda\_vendor\auxlib\path.py

把文件path.py中，「except ImportError: 」修改成「except Exception:「

在運行Anaconda Prompt，輸入conda，效果圖以下：

 這裏問題尚未完全解決，在PyCharm這種編譯器指向Python的時候，仍是會出問題，問題以下：

這時候須要更新Pip，打開Anaconda Prompt，輸入命令conda update conda pip，聯網更新pip

在打開pycharm，右下角會更新一些python信息

而後尚未完，更新完了跑，仍是出問題，問題以下：

 

最後一氣之下，找到D:\ProgramData\Anaconda3\lib\site-packages\setuptools-27.2.0-py3.6.egg，而後刪除（不放心的話，剪切到別的地方）

 

 而後運行，好了。。。。

 

 

但願對踩坑的朋友有幫助。
