I was unable to install the cPickle module using pip:

$ pip --version
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip install cPickle
...
  Could not find any downloads that satisfy the requirement pickle

Attempting installation with pip3 was also unsuccessful:

$ pip3 --version
pip 1.5.6 from /usr/lib/python3/dist-packages (python 3.4)
$ pip3 install cPickle
...
  Could not find any downloads that satisfy the requirement cPickle

Could you help me in understanding why this doesn't work?

Python 2.7 and Python 3.4 include the pickle and cPickle modules already. You do not need to take any extra steps to install them. You can see a list of currently installed modules by typing

help('modules')

from a Python prompt.

  • I have Python 2.7.6 and when I type help('modules'), I do see pickle there but no cpickle. – Roman Dec 05 '16 at 08:16

cPickle is by default part of the standard library, but the capital P could be confusing. You should use:

import cPickle

With the capitial P.
