I'm installing various Python libraries onto an Ubuntu Linux 12.04 LTS VirtualBox VM which I recently created from scratch. This is so I can do some Python-related university work on my own machine. I was advised in resources given to me by my lecturer to run the following commands to get the packages I need up and running:

$ sudo apt-get install python-dev python-numpy python-numpy-dev python-setuptools python-numpy-dev python-scipy libatlas-dev g++ python-pip cython python-imaging
$ sudo pip matplotlib scikit-learn scikit-image pybrain PIL

I quickly found the 2nd command had an error in it, and so I changed it to $ sudo pip install matplotlib ... before re-running it.

However, during the re-run, I came across an error where matplotlib could not build because Freetype was not installed. And so I followed this Stackoverflow post "Ubuntu running `pip install` gives error 'The following required packages can not be built: * freetype'" to get the required libfreetype6 package installed on my system.

This leads onto my current problem. My newest attempts to build matplotlib produce an error accompanied with the following wall-of-text 'pip.log' file:

What is causing my matplotlib build to fail? What can I do to fix it?

    It looks like you're missing `libpng`. Try `sudo apt-get build-dep python-matplotlib`. That *should* install all the dependancies required to actully install MPL from `pip`. – Paul H Feb 12 '14 at 15:16
  • I am currently trying KapelNick's answer and waiting for the packages to install. I will try your solution afterwards, Paul H, to see whether I have obtained the dependency you mentioned. I'll accept a suitable answer shortly afterwards. – jbduncan Feb 12 '14 at 16:28
  • so what happened with your problem? did you solve it yet? –  Feb 12 '14 at 18:25
  • I had a weird issue where installing a particular dependency of matplotlib using your method was freezing my VM, leaving it partially installed. It got messy quickly, so I've re-installed my VM and I've decided to try out Paul H's method first this time around. – jbduncan Feb 12 '14 at 18:47

You can simply get all of the above with a stack which as you can see includes various packages.

sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

It comes from here in case you want to dig more.

It shouldn't be that hard to install packages, especially on Linux, so i recommend trying some alternatives rather than losing time looking for missing dependencies and stuff. Any additional packages can be installed manually.

  • i will edit i think you are right i might have overextended there. thanks –  Feb 12 '14 at 16:16

Although it took some additional fiddling, the answer provided by Paul H in the comments section of the original post was what I was looking for. I have pasted his comment here:

"It looks like you're missing libpng. Try sudo apt-get build-dep python-matplotlib. That should install all the dependancies required to actully install MPL from pip."
