找了一個python大神，解決了一下午都沒發現具體是啥原因，軟件下載了再卸載，在換版本在安裝還是不行，不得已從D盤安裝到了C盤，今天早上無意間看了 ：https://blog.csdn.net/u013567842/article/details/68955214 這篇文章，才發現問題，感謝這個博主

 

解決辦法：

原因是pip安裝Python包會加載我的用戶目錄，我的用戶目錄恰好是中文的，ascii不能編碼。
解決辦法是： 
python目錄 Python27\Lib\site-packages 建一個文件sitecustomize.py 
內容寫： 
import sys 
sys.setdefaultencoding('gbk') 
python會自動運行這個文件。
