Linux下配置pip镜像源遇到的小坑

Linux下pip换源遇到的坑

#1 环境及需求

1.1 环境

CentOS 6.9
Python 3.4

#1.2 需求

pip镜像国外的下载速度慢,需要将pip镜像源换成国内镜像

#2 开始

#2.1 非root用户

在/home/用户名/目录下新建.pip/pip.conf文件

文件内容如下:

[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host=pypi.douban.com

#2.2 使用

pip install get-time

打印的信息中,显示已经换源成功,但是非root用户没有修改文件的权限

[cox@799a3e499eed python2.6]$ pip install get-time

切换root用户

su root

pip install get-time

下载成功,但是很慢,并没有使用国内的镜像源

为什么没有root用户没有使用刚刚配置的国内的镜像源 ???

原来是因为配置的pip.conf文件存在/home/用户名/目录下,这样配置的镜像源只对指定的用户起作用, 使用root权限下载的时候,并不会走pip.conf文件,所以下载很慢

如何配置root用户额镜像源 ???

在~目录下新建.pip/pip.conf文件, 内容同上

[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host=pypi.douban.com

使用root用户下载
