Running the following command:

Answer 1

Check your Internet connection.

It seems that the Internet is unreachable for you. Less likely, PyPi is experiencing temporary problems and you should try connecting later.

Answer 2

Very simple methods step by step:-

1. Download matplotlib(.whl) from http://www.lfd.uci.edu/~gohlke/pythonlibs/

2. matplotlib also Requires numpy , dateutil , pytz , pyparsing , cycler , setuptools

   process: open>python27>>Scripts>copy and paste matplotlib.whlfile

3. open cmd on python27>Scripts> pip install matplotlib-1.5.1-cp27-none win_amd64.whl

I think this is the simplest install method. Just try it if you face again same problem then ping me.

Answer 3

Another possible solution - I found an executable installer here

Didn't find it with Google before.

Answer 4

Try ignoring the cache:

pip install matplotlib --no-cache

No idea how this works, because when it said ConnectionTimeoutError , I assumed that it was not using the cache. If this works for anyone, I'd love to hear an explanation.
