python hashlib не может установить pip

У меня есть скрипт, который зависит от hashlib, но когда я пробую sudo pip install hashlib, я получаю следующее:

$ sudo pip install hashlib

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-BbiB5F/hashlib/

Что я могу сделать, чтобы это исправить?
