通过PyPI镜像安装Python包

有时,我们直接用pip install package_name安装包时,下载很慢,我们可以尝试从PyPI镜像下载包。

这里是镜像列表和目前的状态:
http://www.pypi-mirrors.org/ (另外,http://pypi.v2ex.com也是一个镜像)

要使用镜像,只要修改pip 的配置文件:
http://www.pip-installer.org/en/latest/configuration.html
在unix和macos,配置文件为:$HOME/.pip/pip.conf
在windows上,配置文件为:%HOME%\pip\pip.ini
如果上面的文件不存在,那就新建一个。


例如在Linux下:
vi ~/.pip/pip.conf
增加下面代码(index-url建议使用http://mirrors.aliyun.com/pypi/simple/

[global]
timeout = 60 index
-url = http://<mirror>/simple

配置好后,推荐使用阿里云的镜像,它更新频率比较高,与源在时间上差距很小。

另外,你也可以在install时用参数 i 显式指定镜像,如下

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

pip升级到7.0以后,在使用http镜像进行包安装及升级的时候往往会有如下提示

Collecting beautifulsoup4
The repository located at mirrors.aliyun.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS it is recommended to use HTTPS instead, otherwise you may silence this warning and allow it anyways with ‘–trusted-host mirrors.aliyun.com’.
Could not find a version that satisfies the requirement beautifulsoup4 (from versions: )
No matching distribution found for beautifulsoup4

 

解决办法如下:

1.安装时加入–trusted-host mirrors.aliyun.com参数:

pip install beautifulsoup4 --trusted-host mirrors.aliyun.com

 

2.在pip.conf中加入trusted-host选项,该方法是一劳永逸

[global]
timeout = 60
index-url = http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com
