Installing matplotlib using pip gives error

Question

I am new to python and is using pip to download and install packages. I ran the following code on my command window and it throws an error

pip install matplotlib

And the process starts as

Collecting matplotlib
  Using cached matplotlib-1.5.3-cp27-cp27m-win32.whl
Collecting numpy>=1.6 (from matplotlib)
  Using cached numpy-1.11.2-cp27-none-win32.whl
Collecting python-dateutil (from matplotlib)
  Using cached python_dateutil-2.5.3-py2.py3-none-any.whl
Collecting cycler (from matplotlib)
  Using cached cycler-0.10.0-py2.py3-none-any.whl
Collecting pyparsing!=2.0.4,!=2.1.2,>=1.5.6 (from matplotlib)
  Using cached pyparsing-2.1.10-py2.py3-none-any.whl
Collecting pytz (from matplotlib)
  Using cached pytz-2016.7-py2.py3-none-any.whl
Collecting six>=1.5 (from python-dateutil->matplotlib)
  Using cached six-1.10.0-py2.py3-none-any.whl
Installing collected packages: numpy, six, python-dateutil, cycler, pyparsing, pytz, matplotlib
Exception:
Traceback (most recent call last):
  File "c:\python27\lib\site-packages\pip\basecommand.py", line 215, in main

    with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied: 'c:\\python27\\Lib\\site-packages\\numpy\\core\\multiarray.pyd'

And it gives these traceback errors. I'm unable to figure out what these errors are and how to solve them. Please help. It works perfectly till collecting the packages but at the time of installing it throws errors.

PIP is trying to say "Hi, I downloaded all the packages, but I can't run their installation scripts. Do I have a permission to run scripts in that folder?" — Mohamed Moanis

This normally happens when you already have an instance of python running it's like trying to rename a word file while it is open in word, it won't work. Close all python programs and interpreters and try again. Are you using it on a normal PC? If so I would suggest you download the Anaconda distribution of python. It has most of the packages included, matplotlib being one of them. — Neill Herbst

I guess that was the problem. I restarted cmd and downloaded the version manually by using pip download matplotlib==1.5.3 and then pip install matplotlib==1.5.3 Thanks for your help @NeillHerbst — NISHIT KHARA

If you're using Windows, the easiest way to install many of the numerically-oriented Python packages is to download one of wheels containing pre-compiled binaries from http://www.lfd.uci.edu/~gohlke/pythonlibs/, and install using pip:

pip install SomePackage-1.0-py2.py3-none-any.whl

Make sure to download the right wheel version (Python2 or Python3, 32 bit or 64 bit) for your Python installation.

Open the cmd as administrator

The same error comes after python -m pip install matplotlib

What is happening exactly and what changes should I make ?

Mohamed Moanis Over a year ago

What happens is that the folders pip trying to run scripts from is in the C drive which usually require an administrator access. I edited the answer, try the second way.

I did that as soon as you said it needs permissions. Still that is not working
