Как установить Matplotlib в Ubuntu 14.04?

Мотивация в 14.04: 16.04 багги для использования в производстве. 14.04 является единственным стабильным. 15.10 также является ошибкой. Их выскочка / systemd с runit ужасна.

Я запускаю masi@masi:~/BitTorrentSync/IPython$ sudo -H pip install matplotlib

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-5VdgT2/matplotlib/

, где код ошибки 1 не возвращал соответствующие потоки. Я получил точно такую ​​же ошибку при запуске команды без sudo -H. Это неполная установка, пытаясь использовать модуль, который вы получаете

ImportError: No module named matplotlib.pyplot

Предложение в комментарии. Я успешно выполнил sudo apt-get install libfreetype6-dev libpng12-dev. Я успешно выполняю sudo -H pip install matplotlib. Тем не менее, я получаю предупреждение при запуске модуля matplotlib теперь

/usr/local/lib/python2.7/dist-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
