Я новичок в программировании и пытаюсь загрузить NLTK для работы в чат-боте с Python.На данный момент я использую Python 2.7.Согласно документации для NLTK, «NLTK требует Python версий 2.7, 3.5, 3.6 или 3.7».
Я скачал Homebrew и выполнил команды, предложенные в документации, но получил сообщения об ошибках.

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Согласно документации, доступной по адресу: https://www.nltk.org/install.html
Я попытался выполнить команду "sudo pip install -U nltk", которая вернула ошибки:
ERROR: Complete output from command python setup.py egg_info:
ERROR: error in nltk setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Expected version spec in singledispatch; python_version < "3.4" at ; python_version < "3.4"

ERROR: Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-install-OTcEsN/nltk/
Я также безуспешно попробовал предложение в нижней части страницы документации, а именно: «Для более старых версий Python может потребоваться установить setuptools (см. http://pypi.python.org/pypi/setuptools) и установить pip (sudo easy_install pip)».В результате возникли следующие ошибки:
ERROR: Complete output from command python setup.py egg_info:
