Ошибка lib Mathplot на Python

Я пытаюсь работать на коде python которому нужно mathplotlib. Путем ввода:

python3 mouse_click.py

дает ошибку

ImportError: No module named 'matplotlib'

Для установки

sudo apt-get install python-matplotlib

Результат:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
python-matplotlib is already the newest version.
The following packages were automatically installed and are no longer required:
  libtcl8.5 libtk8.5 tcl8.5 tk8.5
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Это показывает, что все в порядке, и я уже установил его. Но это не.

После этого я попробовал:

sudo apt-get install python3-mathplotlib

Результат:

E: Unable to locate package python3-mathplotlib

Затем я попробовал:

sudo apt-get build-dep python-matplotlib

Вот результат вышеупомянутого кода:

Наконец:

sudo apt-get build-dep python3-matplotlib

Результат:

Я не сделал установил любой Python, потому что ubuntu 14.04 уже имейте Python 3.4.3. Я нуждаюсь в помощи об установке mathplotlib выполнять мой код.
