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 # # written by Joakim Loew for Secret Labs AB / PythonWare # # source: # http:///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。
