Python 패키지를 올바르게 설치하는 방법은 무엇입니까?

Slackware 시스템을 실행하고 Python 코드를 실행하려고 하는데 다음과 같은 오류가 많이 발생합니다.

>>> import urllib2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/urllib2.py", line 91, in <module>
    import hashlib
  File "/usr/lib/python2.6/hashlib.py", line 136, in <module>
    md5 = __get_builtin_constructor('md5')
  File "/usr/lib/python2.6/hashlib.py", line 63, in __get_builtin_constructor
    import _md5
ImportError: No module named _md5

urllib2는 Python을 위한 매우 기본적인 라이브러리로 간주됩니다. Python을 작동시키려면 어떻게 해야 합니까?

그 이유는 이것이 urllib2다음에 의존하는 것 같습니다 praw.https://github.com/praw-dev/praw/issues/135

pip로 설치하려고 하면 다음과 같은 결과가 나타납니다.

Traceback (most recent call last):
  File "setup.py", line 5, in <module>
    from setuptools import setup
ImportError: No module named setuptools

그래서 setuptools를 설치하려고 합니다.
