Windows 下 Python easy_install 的安装
下载安装python安装工具
下载地址：http://pypi.python.org/pypi/setuptools 可以找到正确的版本进行下载。win7 32位可以下载setuptools-0.6c11.win32-py2.7.exe 。
注意：win7 64位必须使用ez_setup.py进行安装。方法是下载ez_setup.py后，在cmd下执行 python ez_setup.py，即可自动安装setuptools。目前没有直接的exe安装版本。
注意2：更新了更简单的办法，可以直接跳转到最后面
下载完成后双击执行安装文件，即可在D:\Program Files\python2.7\scripts下安装easy_install。包含一个easy_install.exe，然后进行环境变量设置，在系统环境变量中做如下设置：(也就是将D:\Program Files\python2.7\scripts添加到环境变量中）
此时可以在控制台看easy_install 是否安装上了。 Microsoft Windows [版本 6.1.7600]

C:\Users\zhuyupeng>easy_install
error: No urls, filenames, or requirements specified (see --help) 上面这种方式不正确，需要使用下面的方式：
C:\Users\zhuyupeng>easy_install virtualenv

安装lxml：
C:\Users\zhuyupeng> 如果直接使用：easy_install lxml
C:\Users\zhuyupeng> easy_install lxml 则会出现下面问题：make sure the developing packages of libxml2 and libxslt are installed windows 可以使用安装.egg 文件的方式来安装：到C:\Users\zhuyupeng> easy_install D:\Program Files\Python2.7\lxml-2.3.py2.7.win32.egg 注：对于*.exe 文件这样也可以安装 通过这样的方式就可以安装成功了：可以通过在控制台输入：easy_install lxml 来查看： Microsoft Windows [版本 6.1.7600]

C:\Users\zhuyupeng> 安装了easy_install 之后安装python的库就很简单了，以后需要安装python的库的话则直接在命令行使用easy_install + libname 比如：
C:\Users\zhuyupeng>easy_install numpy
Searching for numpy
...

Finished processing dependencies for numpy
这是下载下来再安装的：
C:\Users\zhuyupeng>easy_install "D:\Program Files\Python2.7\matplotlib-1.1.0.win
32-py2.7.exe"
...

C:\Users\zhuyupeng> 附一个画爱心的程序：""" '17*x^2 - 16*|x|*y + 17*y^2 = 225' """ import numpy as np import matplotlib.pyplot as plt X = np.arange(-5.0, 5.0, 0.1) Y = np.arange(-5.0, 5.0, 0.1) x, y = np.meshgrid(X, Y) f = 17 * x ** 2 - 16 * np.abs(x) * y + 17 * y ** 2 - 225 fig = plt.figure() cs = plt.contour(x, y, f, 0, colors = 'r') plt.show()

更简单的办法，只需要输入几个命令就ok了：
以下是在IDLE中进行的：
Python 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> from urllib import urlopen
>>> data = urlopen('http://peak.telecommunity.com/dist/ez_setup.py')
>>> open('ez_setup.py','wb').write(data.read())
>>> exit
Use exit() or Ctrl-Z plus Return to exit
>>>

以下是在windows控制台进行的：
