やったこと
python環境をタイトルのとおり構築。
環境
- windows 7
- vagrantで構築したvm
- pythonはpyenvをつかってインストールなので詳細は割愛
※pyenvでのインスト－ルはこちらの通り
※上記までは完了している前提
pandasインストール
$ pip install pandas
matplotlib（可視化ライブラリ）
$ pip install matplotlib

BUILDING MATPLOTLIB
matplotlib: yes [1.4.3]
python: yes [3.4.3 (default, Sep 27 2015, 16:07:11) [GCC
4.4.7 20120313 (Red Hat 4.4.7-16)]]
platform: yes [linux]
REQUIRED DEPENDENCIES AND EXTENSIONS
numpy: yes [version 1.9.3]
six: yes [using six version 1.9.0]
dateutil: yes [using dateutil version 2.4.2]
pytz: yes [using pytz version 2015.6]
tornado: yes [using tornado version 4.2.1]
pyparsing: yes [using pyparsing version 2.0.3]
pycxx: yes [Official versions of PyCXX are not compatible
with matplotlib on Python 3.x, since they lack
support for the buffer object. Using local copy]
libagg: yes [pkg-config information for 'libagg' could not
be found. Using local copy.]
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ms7vpmo7/matplotlib
と、エラー・・・
上記を見る限り、pycxx、libaggのとこで互換性がないなど言われている・・・
が、トライ&エラーを繰り返し、調べ・・・て調べた結果。。。上記が原因ではなく、
Building Matplotlib requires libpng (and freetype, as well) which isn't a python library, so pip doesn't handle installing it (or freetype).
You'll need to install something along the lines of libpng-devel and freetype-devel (or whatever the equivalent is for your OS).
とのことで、pipではなく、yumで下記の通りインストール。
$ sudo yum install -y freetype*
$ sudo yum install -y libpng-devel
$ pip install matplotlib
