NLTK的安裝，NLTK安裝

如果你是2.7版本，並且電腦是64位機器。建議你按照如下步驟進行安裝
Install Python: http://www.python.org/download/releases/2.7.3/
安裝Numpy (optional): http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
安裝Setuptools: http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11.win32-py2.7.exe
安裝 Pip:  https://pypi.python.org/pypi/pip#downloads
安裝PyYAML and NLTK: http://pyyaml.org/wiki/PyYAML

如果出現

Python version 2.7 required, which was not found in the registry

建立一個register.py 檔案，把一下代碼貼進去，

import sys from _winreg import * # tweak as necessaryversion = 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()

運行後

顯示“python 2.7 is already registered”

再安裝setuptools的時候，就能自動識別出來python2.7了。

win7是 64的原因，在安裝python（32位）時，如果選擇只為目前使用者，以上問題是不會出現的，如果選擇所有使用者，那就用上面的方法解決吧。
