文章标签 python 设置 默认 清华

本文主要是介绍PYTHON设置默认清华源，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

首先打开windows的运行窗口输入 %appdata% ，或者打开目“C:\Users\Administrator\AppData\Roaming”

在这里插入图片描述

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 = 6000index-url = https://pypi.tuna.tsinghua.edu.cn/simpletrusted-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

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 
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
