pip安装python库总是下载超时，有什么解决方法吗？

Question

如题，最近经常出现下载超时的情况，怎么也安装不了，有什么解决方法吗？

Answer 1

Create a file ~/.pip/pip.conf with the following content

[global]
index-url = http://b.pypi.python.org/simple
[install]
use-mirrors = true
mirrors = http://b.pypi.python.org

http://pypi.python.org/mirrors

Answer 2

It is recommended to use the mirror: http://e.pypi.python.org. This is the IP of Beijing and will be much faster.
In addition, you can set a timeout = 6000 in the [global] block to avoid incomplete downloading of the installation package when the network is slow.

[global]
timeout = 6000
index-url = http://e.pypi.python.org/simple
[install]
use-mirrors = true
mirrors = http://e.pypi.python.org

Answer 3

You can also specify the installation source of a single library

pip install flask -i http://pypi.v2ex.com/simple

Answer 4

Or try the v2ex source

Create the file pip.conf under ~/.pip/ (if you don’t have one already) and fill in the following content:

[global]
index-url = http://pypi.v2ex.com/simple

Answer 5

Regarding the new version of HTTP insecurity error, I will give you a template.

[global]
timeout = 6000
index-url = http://pypi.douban.com/simple/ 
[install]
use-mirrors = true
mirrors = http://pypi.douban.com/simple/ 
trusted-host = pypi.douban.com

Answer 6

pip install -i https://pypi.doubanio.com/simple/ 包名

The addresses provided by many answers are either closed or redirected, and the new version must use https. It is recommended to use the above one for domestic mirrors.
I personally do not recommend changing the source address by default to avoid security risks.

Answer 7

Check the mirror activity in PyPI Mirror. Just select the appropriate image for the CN region.

The specific configuration method is as follows
Using a mirror
Single Usage:

pip install -i http://<mirror>/simple <package>

Global settings:
Add ~/.pip/pip.conf that includes:

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

Answer 8

The above mainly talks about mirror, another option is proxy:

pip install package --proxy=[代理地址]

Posting some useful Pypi mirrors:

• Douban

• University of Science and Technology of China
