*** PYTHONPATH の指定 [#xe99f947]
- ~/.bashrc に export 文を追加
- &color(red){.bashrc に切った PATH は仮想環境外でも有効になってしまうのでナンセンスな気がする。　仮想環境下でのパスの設定は別途要調査};

export PYTHONPATH="/home/munakata/code/python/vman/lib/python3.6/site-packages:/usr/lib/python36.zip:/usr/lib/python3.6:/usr/li    b/python3.6/lib-dynload:$PYTHONPATH"
