python中安装包出现Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None))…………

问题：

安装包出现Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError

这是由于pip访问国外镜像源的问题，将源转为国内源即可

只需按照以下步骤即可解决

pip install selectivesearch -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

其他源总结：

国内的pip源，如下：

阿里云 http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban) http://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/

使用方法很简单，直接 -i 加 url 即可！如下：

pip install web.py - i http://pypi.douban.com/simple

若是出现以下错误

The respository located at pypi.douban.com is not a trusted or secure host and is being ignored.If this repository is avaiable via HTTPS
it is recommended to use HTTPS instead,otherwise you may silence this warning and allow it anyways with "--trusted-host pypi.douban.com"
Could not find a version that satisfies the satisfies the requirement web,py

解决方式

pip install web.py -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

直接修改配置文件

1. 在路径C:\Users\{用户名}\下建立pip文件夹，然后新建pip.ini文件
   打开文件，将以下内容复制到其中

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

当然centos和windows上的详细配置可以看这里
