我已经在 mac 上安装了一个 Apache 服务器，并以cherrypy 作为我的 web 框架。我打算公开某些涉及 nltk 的服务。我在做同样的事情时收到 500 个内部错误。互联网上的搜索将“AttributeError：'module'对象没有属性'word'”解释为循环依赖问题。我怀疑系统python和nltk的版本差异。

我是 Python 新手，我的调试技能真的很差。请帮忙

import cherrypy
import nltk

class HelloWorld :
    def index(self) :
        return "Hello world !"
    index.exposed=True

    def printHappy(self,age) :
        return age
    printHappy.exposed=True

    def fNouns(self,string):
        text = nltk.word.tokenize(string)
        nounTag=nltk.pos_Tag(text)
        return  nounTag
    fNouns.exposed=True

cherrypy.quickstart(HelloWorld())

当我尝试使用它访问它时http://localhost:8080/fNouns/hey，我收到以下错误（但是http://localhost:8080/printHappy/1234有效！！）

500 Internal Server Error

服务器遇到了一个意外情况，导致它无法完成请求。

您输入了错误的函数名称。nltk.word.tokenize实际上叫做nltk.word_tokenize. 你像这样使用它：

In [1]: from nltk import word_tokenize

In [2]: word_tokenize('i like cats and dogs')
Out[2]: ['i', 'like', 'cats', 'and', 'dogs']

如果您使用错误的名称，则会收到以下错误：

In [3]: import nltk

In [4]: nltk.word.tokenize('i like cats and dogs')
