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()

(2)开始-运行-cmd,把D:\register.py复制进去按回车,出现Python 2.7 is already registered!则表示配置成功。

3、继续安装setuptools
4、安装Pip:开始-运行-D:\Program Files\Python\Scripts\easy_install pip
5、安装PyYAML和NLTK:开始-运行-D:\Program Files\Python\Scripts\pip install pyyaml nltk
6、测试安装:开始-所有程序-Python 2.7-IDLE(Python GUI),输入import nltk,无错误表示成功。
