"Learn Python with me" Python's package management tool

Just started to learn python, read the document and other people's blog introduction to install the package with Easy_install, Setuptools, and some use of pip,distribute, then what is the relationship between these tools, look at the following diagram to understand

You can see that distribute is the replacement of Setuptools, and Pip is the replacement of Easy_install.

Refer to Http://guide.python-distribute.org/installation.html#installing-pip for these package tools

Here's a quick introduction:

Distribute is an enhancement to the standard library Disutils module, and we know that disutils is primarily used to package and distribute packages more easily, especially for packages that have dependencies on other packages.

Distribute was created because the Setuptools package is no longer maintained.

Installing distribute

Can be installed through the distribute_setup.py script distribute can also be installed through Easy_install, Pip, source files, but the use of distribute_setup.py to install is the simplest and popular way

$ curl-0 http://python-distribute.org/distribute_setup.py

$ sudo python distribute_setup.py

Pip is a tool for installing the Python package, providing an installation package that lists the packages that have been installed, the upgrade package, and the ability to uninstall the package.

Pip is a replacement for Easy_install, which provides the same functionality for finding packages as Easy_install, so packages that can be installed using Easy_install can also be installed using PIP.

Install PIP

PIP installation can be via source code package, Easy_install or script.

Here are the various installation methods:

Source Code mode:

$ wget http://pypi.python.org/packages/source/p/pip/pip-0.7.2.tar.gz (replace with latest package) $ tar xzf pip-0.7.2.tar.gz$ CD pip-0.7.2 $ python setup.py Install

Easy_install:

$ easy_install pip

get_pip.py script:

$ curl-0 https://raw.github.com/pypa/pip/master/contrib/get-pip.py

$ sudo python get-pip.py

OK, here's a look at the use of PIP
