据小编统计绝大多数朋友对这一问题很棘手，今天小编给大家分享这一问题的解决方案，一起看看吧

使用pip 提示更新：

You are using pip version 18.1, however version 20.0.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

输入python -m pip install --upgrade pip出现问题

这是因为服务器连接超时，使用下方代码即可解决（因为pip源在国外，所以连起来比较慢，可以改用国内的源）

python -m pip install --upgrade pip -i https://pypi.douban.com/simple

问题解决

安装其他包也可使用此方法加快下载速度
比如安装pip install scipy

pip install scipy -i https://pypi.douban.com/simple
