pipはPython 2.7.9以降、Python 3.4以降のバージョンにはデフォルトでインストールされています。

2.7.6にはインストールされていないので、以下を実行してください。

1. get-pip.pyをダウンロードしてください。https://gist.github.com/whaison/b20a7cb50f0d4c0033e765fe41f6ae74
2. ファイルをダウンロードしたディレクトリに移動し以下のコマンドを実行してください。

1	$ sudo python get-pip.py

これでpipのインストールは完了です。

pipがデフォルトでインストールされている場合もpipのバージョンが低い可能性がありますので、念のためpipをアップデートした方がいいでしょう。以下のコマンドでアップデートすることができます。

Linux, OS Xの場合

1	$ sudo pip install -U pip

Windowsの場合

1	$ sudo python -m pip install -U pip

9以降、Python 3.4以降のバージョンにはデフォルトでインストールされています。インストールされていない場合は、以下を実行してください。

1. get-pip.pyをダウンロードしてください。https://gist.github.com/whaison/83dbf14015bcd2f937bba8509a076428
2. ファイルをダウンロードしたディレクトリに移動し以下のコマンドを実行してください。

1	$ sudo python get-pip.py

これでpipのインストールは完了です。

とはいえ、修正対象のソースコードがあまりにも多いときには、全てを手動でチマチマ直していく作業はあまりに大変そう。
そんな大変な作業を肩代わりしてくれるツールとして autopep8 がある。

ところで、それまで PEP8 に準拠していなかったプロジェクトを準拠させようとしたときなんか、色んなソースコードのファイルで膨大な数の警告が出てうんざりすることになるはず。
だとすると、ディレクトリを再帰的に調べながら pep8 で警告が出ているソースコードのファイルに対して autopep8 にかけまくれると便利なんじゃなかろうか。
そこで、以下のワンライナー。

cmd.FBXExportApplyConstantKeyReducer が機能してないので、
maya.mel.eval("FBXExportApplyConstantKeyReducer -v false")でつまりmelでやるしかないようだ。
