python 2.7安装

下载python 2.7：

安装

nltk安装

1、下载nltk，， 安装。

2、安装时会出现以下错误：python version 2.7 required, which was not found in the registry。

解决办法：

(1)新建一个register.py文件，把以下代码粘贴进去，保存到d盘。

# script to register python 2.0 or later for use with win32all 
# and other extensions that require python registry settings 
#

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。
