Because of the project, I need to study python deeply. Back-end programs rely on various software packages, such as MySQLdb. Beginners may not be familiar with how to quickly install the required python packages. Commonly used python package installation and management are easy_install, setuptools, pip,distribute.

This article introduces pip--- "A tool for installing and managing Python packages."

Install pip

First, get the script get-pip.py.

Wget https://bootstrap.pypa.io/get-pip.py

Python get-pip.py

Note:

Get-pip.py will help you install setuptools, and if you have already installed it, it will run the upgrade command:

Pip install-U setuptools

Upgrade pip

Pip install-U pip

Install the python package

Pip install SomePackage # download the latest version if you do not specify a version

Pip install SomePackage==1.0.4 # download the specified version

For example, download and install MySQLdb

Root@rac3:~/scripts# > pip install MySQL-python
