Install MatPlotLib 1.2.x on OS X Lion 10.7.4 and Python 3.2.2

Question

A few days ago I asked a question about installing numpy on the same system. Fortunately, I managed to solve this myself, but unfortunately, I am now stuck trying to install matplotlib.

First of all, I tried the current distributed version, but I had no luck, so I decided to download the git repository and try it. I'm so far away:

• modified the make.osx file so that it works in Python 3:
  • import urllib import urllib.request
  • urllib.urlretrieve() → urllib.request.urlretrieve()

Even after that, I still had a problem with this without finding freetype2 headers. I googled around and found that I could solve this by editing the line in setupext.py :

• 'darwin' : [], → 'darwin' : ['/usr/local'],

However, I still get an error when using the make.osx file. This is how I call the file from the terminal:

• sudo make -f make.osx PREFIX=/usr/local PYVERSION=3.2 fetch deps mpl_build mpl_install

I understand that matplotlib is not officially supported in Python 3, but I thought that maybe someone at least managed to get it to compile / install?

Any help would be greatly appreciated

I have included the error I get below:

Ok ... I think I managed to install matplotlib to install ...

• First of all you need to install numpy . I have instructions for this in another post: install numpy

• Now open Terminal and clone the git repository for matplotlib (assuming you have git installed):

  • git clone git://github.com/matplotlib/matplotlib.git (this may take some time)

• Once the clone is complete, open your user folder in Finder

• In your user folder, open the matplotlib directory

• A file named `make.osx 'is opened using TextEdit (or similar)

• Change the following lines:

  • MACOSX_DEPLOYMENT_TARGET=10.6
  • OSX_SDK_VER=10.6

  To:

  • MACOSX_DEPLOYMENT_TARGET=10.7
  • OSX_SDK_VER=10.7

• Change the following lines:

  • ${PYTHON} -c 'import urllib; urllib.urlretrieve("${ZLIBURL}", "${ZLIBFILE}")' &&\ ${PYTHON} -c 'import urllib; urllib.urlretrieve("${PNGURL}", "${PNGFILE}")' &&\ ${PYTHON} -c 'import urllib; urllib.urlretrieve("${FREETYPEURL}", "${FREETYPEFILE}")'

  To:

  • ${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${ZLIBURL}", "${ZLIBFILE}")' &&\ ${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${PNGURL}", "${PNGFILE}")' &&\ ${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${FREETYPEURL}", "${FREETYPEFILE}")'

• Save changes

• Open setupext.py in standby mode

• Find the line 'darwin' : [], and change it to 'darwin' : ['/usr/local'],

• Save file

• Open Terminal and enter the following:

  • sudo make -f make.osx PREFIX=/usr/local PYVERSION=3.2 fetch deps mpl_build mpl_install

• After a while, matplotlib should be installed in the following directory:

  • /usr/local/lib/Python3.2/site-packages/

• Open the above directory, as well as the following directory:

  • /Library/Python/3.2/site-packages/

• Copy / move the following directories from /usr/local/lib/Python3.2/site-packages/ to /Library/Python/3.2/site-packages/ :

  • dateutil
  • matplotlib
  • mpl_toolkits

• matplotlib must be installed

• If you open idle and enter import matplotlib , it should not return an error

• I tried matplotlib/examples/user_interfaces/embedding_in_qt4_wtoolbar.py file and it seems to work fine

Hope someone finds this helpful!

Thanks again for your help,

Adam.
