Question

当我尝试在python 3.5.2_2中导入nltk时，我收到以下消息：

>>> import nltk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/site-packages/nltk/__init__.py", line 117, in <module>

    blankline_tokenize = BlanklineTokenizer().tokenize

    RegexpTokenizer.__init__(self, r'\s*\n\s*\n\s*', gaps=True)
  File "/usr/local/lib/python3.5/site-packages/nltk/tokenize/regexp.py", line 119, in __init__
    self._regexp = compile_regexp_to_noncapturing(pattern, flags)
  File "/usr/local/lib/python3.5/site-packages/nltk/internals.py", line 54, in compile_regexp_to_noncapturing
    return sre_compile.compile(convert_regexp_to_noncapturing_parsed(sre_parse.parse(pattern)), flags=flags)
  File "/usr/local/lib/python3.5/site-packages/nltk/internals.py", line 50, in convert_regexp_to_noncapturing_parsed
    parsed_pattern.pattern.groups = 1
AttributeError: can't set attribute

我尝试用pip3重新安装它，我仍然遇到同样的问题......如何在OSX中正确安装NLTK？以及如何解决这个问题？

Answer 1

这可能有效

转到http://www.lfd.uci.edu/~gohlke/pythonlibs/
下载nltk-3.2.1-py2.py3-none-any.whl
将命令行中的文件夹更改为下载该whl文件的位置
现在写C:/windows/python35/scripts/pip install nltk-3.2.1-py2.py3-none-any.whl

当然，如果他们不匹配

Answer 2

我通过使用pip3 nltk和sklearn升级解决了这个问题：
