Python 2.7安装
下载Python 2.7:http://www.python.org/ftp/python/2.7.6/python-2.7.6.amd64.msi
安装
NLTK安装
下载NLTK: http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11.win32-py2.7.exe
安装。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。

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()
继续安装setuptools
安装Pip:开始-运行-D:\Program Files\Python\Scripts\easy_install pip
安装PyYAML和NLTK:开始-运行-D:\Program Files\Python\Scripts\pip install pyyaml nltk
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。
