I have python version 3.3. I did install pip and now trying to install matplotlib and numpy.

pip install matplotlib
pip install numpy

I get these errors:

File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/distutils/sysconfig.py", line 191, in customize_compiler

    _osx_support.customize_compiler(_config_vars)

Do you have a compiler such a gcc installed on your system? –  shuttle87 Jan 17 at 19:13
    
You need a C compiler to build python extensions written in C. pip essentially just grabs a source tarball and tries to build it. For the most part, it doesn't deal with pre-built binaries. It looks like you're on OSX. If so, you'll need to install XCode (or a stripped-down equivalent). Alternately, you can use pre-built binaries to install matplotlib, numpy, etc (just make sure they're built against the same python executable that you're using). Another option is python distributions such as Anaconda, Canopy, etc. –  Joe Kington Jan 17 at 19:14
    
@Joe Kington, I downloaded xcode and installed it. I still get the same error. –  user1471980 Jan 17 at 20:07

Numpy requires a C compiler in order to be installed. This error message suggests to me that you do not have a C compiler installed or that pip can't find it.

Alternatively you might be able to source the binaries for numpy if you do not have a compiler available to you. See the numpy website for more installation information: http://docs.scipy.org/doc/numpy/user/install.html

I found a simple export CC=gcc fixed my problem. (OSX with Xcode installed but same error)

this worked for me (OSX 10.8.5)

install Xcode (from App store)

start Xcode

in its preferences, download, choose Command Line Tools wait for it to install

you can quit Xcode

in terminal :

CC=gcc

pip3 install matplotlib

pip3 install six

I run python 3.4 recently downloaded I had to get six on top of matplotlib to get pyplot to run properly
