Mac環境でPython3.4にmatplotlibをインストールする方法

Pythonのライブラリ、matplotlibをMac環境にインストールする手順です。

環境

手順

freetypeとlibpngをインストールする
% brew install freetype
 
==> Installing freetype dependency: libpng
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/libpng-1.6.14.mountain_lion.bottle.tar.gz
######################################################################## 100.0%
==> Pouring libpng-1.6.14.mountain_lion.bottle.tar.gz
🍺  /usr/local/Cellar/libpng/1.6.14: 17 files, 1.3M
==> Installing freetype
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/freetype-2.5.3_1.mountain_lion.bottle.1.tar.gz
######################################################################## 100.0%
==> Pouring freetype-2.5.3_1.mountain_lion.bottle.1.tar.gz
🍺  /usr/local/Cellar/freetype/2.5.3_1: 60 files, 2.6M
matplotlibをインストールする
pip3 install matplotlib
matplotlibをインストールする
sudo ARCHFLAGS=-Wno-unused-result pip3 install matplotlib

動作確認

下記のコマンドを実行し円グラフが表示されれば、正常にインストールが完了しています。

matplotlibの動作確認
python3 -c 'import matplotlib.pyplot as pyplot; pyplot.pie([1,2,3]); pyplot.show()'

インストールエラーが発生するときは

下記のようなエラーが発生するときは、freetypeやlibpngのインストールの有無、コンパイルオプションの有無などを確認しましょう。 

% pip3 install matplotlib
