本文介绍了如何在不同操作系统上安全地安装Python包管理器pip，包括安装过程、升级setuptools以及使用pip安装特定库如xlrd的方法。

PIP:
Python & OS Support

pip works with CPython versions 2.6, 2.7, 3.2, 3.3, 3.4 and also pypy.

pip works on Unix/Linux, OS X, and Windows.

pip included with Python

Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip by default [1], so you may have pip already.

Install pip

To install pip, securely download get-pip.py. [2]

Then run the following (which may require administrator access):

python get-pip.py

If setuptools is not already installed, get-pip.py will install setuptools for you. [3]

To upgrade an existing setuptools, run pip install -U setuptools.

Additionally, get-pip.py supports using the pip install options and the general options. Below are some examples:

Install from local copies of pip and setuptools:

python get-pip.py --no-index --find-links=/local/copies

Install to the user site [4]:

python get-pip.py --user

Install behind a proxy:

python get-pip.py --proxy="[user:passwd@]proxy.server:port"

setuptools安装好后，
(1)cd /d E:\pip-7.1.2
(2)python setup.py install
https://pypi.python.org/pypi/pip
