如果你是2.7版本，并且电脑是64位机器。建议你按照如下步骤进行安装
Install Python: http://www.python.org/download/releases/2.7.3/
安装Numpy (optional): http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
安装Setuptools: http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11.win32-py2.7.exe
安装 Pip:  https://pypi.python.org/pypi/pip#downloads
安装PyYAML and NLTK: http://pyyaml.org/wiki/PyYAML

如果出现

Python version 2.7 required, which was not found in the registry

新建一个register.py 文件，把一下代码贴进去，

import sys
 
from _winreg import *
 
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
 
regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
    installpath, installpath, installpath
)
 
def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"
 
if __name__ == "__main__":
    RegisterPy()
运行后

显示“python 2.7 is already registered”

再安装setuptools的时候，就能自动识别出来python2.7了。

win7是 64的原因，在安装python（32位）时，如果选择只为当前用户，以上问题是不会出现的，如果选择所有用户，那就用上面的方法解决吧。
