下載Python 2.7：官網下載地址

安裝

NLTK安裝

1、下載NLTK，下載地址，?安裝。

2、安裝時會出現以下錯誤：Python version 2.7 required, which was not found in the registry。

解決辦法：

(1)新建一個register.py文件，把以下代碼粘貼進去，保存到D盤。

# 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)開始-運行-cmd，把D:\register.py復制進去按回車，出現Python 2.7 is already registered！則表示配置成功。

3、繼續安裝setuptools

4、安裝Pip：開始-運行-D:\Program Files\Python\Scripts\easy_install pip

5、安裝PyYAML和NLTK：開始-運行-D:\Program Files\Python\Scripts\pip install pyyaml nltk

6、測試安裝：開始-所有程序-Python 2.7-IDLE(Python GUI)，輸入import nltk，無錯誤表示成功。
