Why can't I install cPickle | Pip needs upgrading?

Question

When trying to install cPickle using pycharm I get this:

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Edwin\AppData\Local\Temp\pycharm-packaging\cpickle
You are using pip version 7.1.2, however version 8.1.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

So then when I go command prompt to type in:

python -m pip install --upgrade pip

I get this:

'python' is not recognized as an internal or external command, operable program or batch file.

So how do I install cPickle?

BTW: I am using windows & python 3.5.1

If you open a command prompt and type `python` in, do you get the same thing? — code11, Oct 24 '16 at 17:09
Python probably needs to be added to your environment variables: http://stackoverflow.com/questions/3701646/how-to-add-to-the-pythonpath-in-windows-7 — A.Kot, Oct 24 '16 at 17:09
I thought `cPickle` was part of the [standard library](https://docs.python.org/2/library/) in 2.7 anyway? — roganjosh, Oct 24 '16 at 17:11
`pip` is python module like `cPickle` - if you know where/how to install `cPickle` with `PyCharm` then try the same way upgrade `pip` with `PyCharm`. — furas, Oct 24 '16 at 17:12
If you're in python 3 then I'm reasonably sure that `pickle` is the same as the `cPickle` from Python 2, and the Python 2 `pickle` was removed. — roganjosh, Oct 24 '16 at 17:13
@roganjosh yes you are right. It is just pickle :D: EDIT: Though does anyone know how to upgrade pip — Edwin Shepherd, Oct 24 '16 at 17:14
For reference if anyone lands on this question somehow: https://docs.python.org/3.1/whatsnew/3.0.html#library-changes Unfortunately, I'm not sure how to solve the issue with upgrading pip. — roganjosh, Oct 24 '16 at 17:15
@roganjosh and I have tried just typing in python and get the same thing. — Edwin Shepherd, Oct 24 '16 at 17:31
Then at a complete guess, you're pointing `pycharm` to some python installation file that hasn't actually been installed on Windows itself. — roganjosh, Oct 24 '16 at 17:33

As suggested in the comments, this is most likely because Python is not added to your environment variables. If you do not want to touch your environment variables, and assuming your Python is installed in C:\Python35\,

Navigate tp C:\Python35\ in Windows Explorer
Go to the address bar and type cmd to shoot up a command prompt in that directory

Alternatively to steps 1 and 2, directly shoot up a command prompt, and cd to your Python installation Directory (default: C:\Python35)

Type python -m pip install pip --upgrade there

Thanks this also allowed me to install a bunch of other libraries :D — Edwin Shepherd, Oct 24 '16 at 18:30
