本文为大家分享了python2.7和NLTK安装教程,具体内容如下

系统:Windows 7 Ultimate 64-bits

Python 2.7安装

下载Python 2.7:官网下载地址

安装

NLTK安装

1、下载NLTK,下载地址, 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 
#

# 
# modified by Valentine Gogichashvili as described in http://www.mail-archive.com/distutils-sig@python.org/msg10512.html 
 
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。
