-------------到此为止----------------
在用户文件夹新建个pip文件夹
再在pip文件夹新建个pip.ini，写入：
[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host=pypi.douban.com
保存好，以后下载python库就会默认使用该镜像，速度很快！！
下面就是一键安装python库的代码了
import os
import re
def getTxt():
txt = open("支持库.txt","r").read()#读取需要安装的第三方库
return txt
kusTxt=getTxt()
words=kusTxt.split(',')
for word in words:
os.system("pip install " + str(word))
print("{}成功安装".format(word))
