Python Switches the PIP installation source in a detailed way _python

First, Pip introduction

The PIP is the tool that installs the Python package, provides the installation package, lists the packages that have been installed, upgrades the packages, and uninstalls the package features.

The PIP is a replacement for Easy_install and provides the same easy_install as the lookup package, so packages that can be installed using Easy_install can also be installed using the PIP.

Second, the source configuration under Linux

Check if the pip.conf file exists

>> CD ~

>> mkdir. Pip

>> ls ~/.pip

Third, edit the source

Scenario 1: Direct Editing pip.conf

sudo vi ~/.pip/pip.conf
