pip的幺蛾子

1.pip的时候出现Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None))…………

一、原因

pip的时候各种关卡了它的网速，导致网速过慢或者安装失败

二、解决方法(一劳永逸)

国内的pip源，如下：

阿里云

中国科技大学

豆瓣(douban)

清华大学

中国科学技术大学

通过配置文件自动调取默认的源，经实测，速度杠杠，方法如下

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=mirrors.aliyun.com

 
 

 
 

2. Linux下，修改 ~/.pip/pip.conf (没有就创建一个文件夹及文件。文件夹要加“.”，表示是隐藏文件夹)
   在文件上写入上面配置文件中的内容
