I am trying to install numpy (so that I can run matplotlibs) for python 3.3 on Mac Mavericks. I have a Windows machine and was able to install everything correctly by simply downloading the .exe files. However, I am very new to the Mac world, and have never installed anything via command line before.

I have downloaded Anaconda and also XCode.

I have tried: 

pip install numpy

and I get the following output:

Requirement already satisfied (use --upgrade to upgrade): numpy in ./anaconda/lib/python2.7/site-packages

It looks like it has 2.7 installed already, but I want 3.3! So, next I tried:

pip-3.3 install numpy

and I get the following output:

pip-3.3: command not found

I have tried to use anaconda after these have failed (having never used anaconda before):

conda create -n myenv python=3
conda install -n myenv numpy scipy matplotlib ipython

After everything was said and done, I got this message:

# All requested packages already installed.
# packages in environment at /Users/username/anaconda/envs/myenv:
#
ipython                   2.2.0                    py34_1  
matplotlib                1.3.1                np18py34_1  
numpy                     1.8.2                    py34_0  
scipy                     0.14.0               np18py34_0

This didn't work either when I attempted to import matplotlib into Python 3.3. It appears to me that this has not installed numpy for 3.3, but for 3.4.

So, I installed Python 3.4. However, it looks like there are compatibility issues between matplotlib and 3.4, so back to 3.3... Additionally, I could not import numpy into 3.4 anyway.

A number of the topics on here where people posted similar problems had OS Lion. As a new Mac person, I can't seem to follow those directions because my version is the newer Mavericks. I looked here, for example: NumPy in IDLE (Python 3.3.2) on Mac OSx 10.8

When I type

which python

into the terminal, I get 

/Users/username/anaconda/bin/python

I do not get 

/Library/Frameworks/Python.framework/Versions/3.3

like the user in that topic suggested I should. In fact, the /Library folder appears to be hard to find on Mavericks.. But, I figured out how to make ~/Library visible. I next

cd Library/Frameworks
ls

and saw:

EWSMac-GC.framework

There was no Python.framework. At this points, I feel like I should have that directory in order to continue. Perhaps not. I am lost at how to continue at this point, and if anyone has any suggestions, it would be appreciated.

I now have numpy installed correctly for Python 3.4, but not Python 3.3.

What I did from terminal:

cd ../..
pwd

output:

/

commands: 

cd usr/local/bin
ls

output:

2to3            python3-32      pythonw3.3
2to3-3.3        python3-config      pythonw3.3-32
2to3-3.4        python3.3       pyvenv
brew            python3.3-32        pyvenv-3.3

pydoc3.3        python3.4m-config   wish8.6
pydoc3.4        pythonw3
python3         pythonw3-32

commands:

pip3 install numpy

There was a lot of output, many lines that looked like:

 Downloading numpy-1.8.2-cp34-cp34m-macosx_10_6_intel.macosx_10_9_intel.macosx_

And then this output:

10_9_x86_64.whl (12.0MB): 12.0MB downloaded
Installing collected packages: numpy
Successfully installed numpy
Cleaning up...

This command installed numpy for 3.4, and not 3.3, as intended. As stated above, I now have both on my system. I don't know if it would have installed for 3.3 if I had completely uninstalled 3.4 first.

I tried to install numpy for 3.3:

pip3 install numpy python3.3

output:

Requirement already satisfied (use --upgrade to upgrade): numpy in /Library/Framework/Python.framework/Versions/3.4/lib/python3.4/site-packages
Downloading/unpacking python3.3
Could not find any downloads that satisfy the requirement python3.3
Cleaning up...
No distributions at all found for python3.3

I tried importing numpy from python 3.4 and it worked. However, my primary goal was to use matplotlib. I attempted to install matplotlib from the command line.

pip3 install matplotlib

This worked, and now I can use matplotlib in python 3.4 and IDLE for 3.4.

Unfortunately, this doesn't satisfy requirements for Python 3.3... But for now, 3.4 is probably OK too.

install python (matplotlib numpy integrating and more ...) through Homebrew, an installer libraries
