Python 更改 PyPI 源

使用PIP管理Python包非常方便,关于PIP的使用可以参考如下链接:
Linux安装pip及使用
http://www.cndba.cn/Expect-le/article/110

https://www.cndba.cn/dave/article/2261
https://www.cndba.cn/dave/article/2261

但PIP模式用的是https://pypi.python.org/作为源,其访问速度太慢。 所以建议使用国内的PIP源代替。 目前可用替代的PIP源有:

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

指定Pip源有两种方法:

1) 在使用pip时通过-i参数指定,如:
[dave@www.cndba.cn pip-9.0.1]# lsb_release -a
LSB Version:    :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID:    RedHatEnterpriseServer
Description:    Red Hat Enterprise Linux Server release 6.7 (Santiago)
Release:    6.7
Codename:    Santiago
[dave@www.cndba.cn pip-9.0.1]#
[dave@www.cndba.cn pip-9.0.1]# python -V
Python 2.6.6
[dave@www.cndba.cn pip-9.0.1]# pip install psutil -i https://pypi.mirrors.ustc.edu.cn/simple/
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

如果报错,可以再加上—trusted-host选项:https://www.cndba.cn/dave/article/2261https://www.cndba.cn/dave/article/2261

pip install psutil -i https://pypi.mirrors.ustc.edu.cn/simple/ --trusted-host pypi.mirrors.ustc.edu.cn

这里提示我们,Python 2.6 将不在倍Python 核心团队支持,让我们升级Python版本。 这里我们用的是Linux 6.7。 默认Python版本是2.6.6。 在Linux 7.x中,默认Python的版本就是2.7了。 https://www.cndba.cn/dave/article/2261

2) 配置成默认的源

第一种方法,每次都要指定源,比较麻烦。所以可以通过指定配置文件,来修改默认的PIP源。https://www.cndba.cn/dave/article/2261

https://www.cndba.cn/dave/article/2261

修改配置文件,如不存在,则创建:

https://www.cndba.cn/dave/article/2261
https://www.cndba.cn/dave/article/2261

linux的文件在~/.pip/pip.conf,
windows在%APPDATA%/pip/pip.ini),

https://www.cndba.cn/dave/article/2261

[dave@www.cndba.cn ~]# mkdir ~/.pip/
[dave@www.cndba.cn ~]# touch ~/.pip/pip.conf

添加以下内容:

[dave@www.cndba.cn ~]# cat ~/.pip/pip.conf 
[global]
index-url = https://pypi.mirrors.ustc.edu.cn/simple/
[install]
trusted-host= pypi.mirrors.ustc.edu.cn

这样在使用pip来安装时,会默认调用该镜像。

[dave@www.cndba.cn ~]# pip install ab

这里成功的使用了USTC的源,而不是默认的。

人的一生应该是这样度过的:当他回首往事的时候,他不会因为虚度年华而悔恨,也不会因为碌碌无为而羞耻;这样,在临死的时候,他就能够说:“我的整个生命和全部精力,都已经献给世界上最壮丽的事业....."
