Re: [Matplotlib-users] Matplotlib "show()" error Mac OS X Lion

[Ludwig S. <lud...@gm...>]

Hi Bedartha and others,  

I have matplotlib 1.1.0 running fine on Mac OS X Lion with TkAgg, Qt4Agg, MacOSX and mplh5canvas ;-) backends in good working condition. My humble opinion is that this works because I do not try to replace System Python with my own version. Given that Lion ships with Python 2.7.1, I do not feel the need to upgrade it to Python.org's 2.7.2 and potentially endure these kinds of installation woes. My current installation instructions for NumPy / SciPy / matplotlib / IPython on Lion ("current" because this is quite a moving target!) can be condensed as follows:

- use homebrew as far as possible (but don't use it to install Python, doh!)
- brew install pkg-config gfortran zeromq pyqt (follow homebrew instructions for PYTHONPATH settings for pyqt dependencies)
- use the System NumPy 1.5.1 - it's good enough for my purposes
- build git version of SciPy using gcc-4.2 - unfortunately still a (slight) pain until next stable release
- sudo easy_install readline nose pyzmq Pygments ipython matplotlib

The detailed instructions are available upon request…

Once you have pkg-config installed via homebrew or otherwise, you can literally just easy_install matplotlib! (Thanks to JDH for recently updating the PyPI repository)

Regards,
Ludwig
