NLTK3.2.4环境搭建

系统环境：win7 32位

python：2.7.13，后改为3.6.1

安装NLTK

从网站下载：http://www.nltk.org/，完成后双击安装，但提示Python version -32 required, which was not found in the registry.

从网上搜索到以下解决方案：

新建文件D:\register.py，通过脚本建立注册信息

#===========================register.py=======================================##
#!/usr/bin/env python
# -*- coding:utf-8 -*-
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!")

RegisterPy()

打开cmd，执行

运行安装文件，仍然失败= =（有大神能解决的请私信或留言 谢谢！）

于是放弃了中文版的NLP with Python，重投http://www.nltk.org/book/。

安装最新版python3.6.1，cmd中直接执行

py –m pip install nltk

安装成功。

在IDLE中输入命令

>>>import nltk
>>>nltk.download()

终于出现如下NLTK Downloader界面


下载完毕后，就可以在IDLE中加载NLTK并使用了。

>>>from nltk.book import *
