首先打开windows的运行窗口输入 %appdata% ，或者打开目“C:\Users\Administrator\AppData\Roaming”
在新弹出的窗口新建一个pip的文件夹，进入文件夹后，创建一个pip.ini的文件，在文件中写入如下内容：
[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn
文件内容保存好后，使用pip安装第三方库即可从清华源下载。
问题一：python安装django报错
[C:\~]$ pip install django
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple

ValueError: check_hostname requires server_hostname
可以看到最后一行报错：ValueError: check_hostname requires server_hostname
解决办法：查看电脑是否有代理的存在，如果有代理需要关闭代理。
问题二：pip安装第三方库报错
[root@localhost ~]# python -m pip install ipython
/usr/local/bin/python: No module named pip
解决办法如下：
python3可以使用这个脚本，https://bootstrap.pypa.io/get-pip.py
python2可以使用如下脚本
# python2解决办法
[root@localhost ~]# wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
[root@localhost ~]# python get-pip.py
