Today, I will talk to you about the reasons for the failure of python pip install under Linux, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

Question:

Retrying (Retry (total=4, connect=None, read=None, redirect=None, status=None) after connection broken by 'ConnectTimeoutError appears in the installation package

Solution:

Pip install selectivesearch-I http://pypi.douban.com/simple-- trusted-host pypi.douban.com

There is a problem with the system using the source by default and the installation failed.

The use method is very simple, directly-I plus url can! As follows:

Pip install pip-i pip install-- upgrade pip-I https://pypi.tuna.tsinghua.edu.cn/simple/

If there is an error in untrust, you can use a website that begins with https, or use the command:

Pip install selenium-I http://pypi.douban.com/simple-- trusted-host pypi.douban.com

If you want to configure it as the default source, the method is as follows:

Need to create or modify configuration files (usually created)

The file of linux is in ~ / .pip/pip.conf

Windows at% HOMEPATH%\ pip\ pip.ini)

Modify the content as follows:

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

This way, when installing using pip, the image will be called by default.

The python scripts that temporarily install packages from other sources are as follows:

#! / usr/bin/python import os package = raw_input ("Please input the package which you want to install!\ n") command = "pip install% s-I http://pypi.mirrors.ustc.edu.cn/simple-- trusted-host pypi.mirrors.ustc.edu.cn"% packageos.system (command)

I used ananconda to change the source method:

# see what kind of conda config the current cofig is-- show# configuration source conda config-- add channels' https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'conda config-- set show_channel_urls yes # Delete source # conda config-- remove channels'. After reading the above, do you have any further understanding of the reason for the failure of python pip install under Linux?
