最近論文需要用到python做數據分析，python語法簡單，但是Windows下安裝第三方包惡心的要命，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，還有好幾個其他的統計包也是如此，整暈了算。
看網上有些python大牛推薦Anaconda，可以解決包的問題，於是卸載本地的python，從官網上下了個Anconda玩玩，結果遇到新問題。
問題如下：

經過一番查找，解決方法如下：
問題解決原鏈接(英文)：https://github.com/conda/conda/pull/5496
找到你的Anaconda安裝目錄中的path.py，詳細路徑為：D:\ProgramData\Anaconda3\Lib\site-packages\conda\_vendor\auxlib\path.py
把文件path.py中，“except ImportError: ”修改為“except Exception:“
在運行Anaconda Prompt，輸入conda，效果圖如下：
這里問題還沒有徹底解決，在PyCharm這種編譯器指向Python的時候，還是會出問題，問題如下：
這時候需要更新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
然后還沒有完，更新完了跑，還是出問題，問題如下：
最后一氣之下，找到D:\ProgramData\Anaconda3\lib\site-packages\setuptools-27.2.0-py3.6.egg，然后刪除（不放心的話，剪切到別的地方）
然后運行，好了。。。。
希望對踩坑的朋友有幫助。
