python could not install any script

I installed python from brew

brew install python

then installed pip

sudo easy_install pip

in Terminal

$ which easy_install
/usr/bin/easy_install

$ which python
/usr/bin/python

But then when I want to install any Python script I get this:

Here's an image of the problem:

まず Terminal で報告されている brew install python、easy_install、python のパスを比較し、次にどのインストールがパッケージを処理しているかを特定します。リポジトリのファイルやテストについては触れられていません。完了とするには、再現可能な診断と、インストールの不一致に対する文書化された修正が必要です。
