pip

以前、easy_install をインストールしたけど、最近ではパッケージ管理に pip を使うのが一般的のようだ。
pip 自体は easy_install を使ってインストールする。

^o^ > python -m easy_install pip

なにやらメッセージがいろいろ出て、無事インストールできたようだ。

^o^ > pip --version

ためしに、テンプレートエンジンの Jinja2 をインストールしてみる。

Cleaning up...

C extension がコンパイルできない、と言う警告が出てるけど、Plain-Python のインストールが成功した、と書いてある。一応成功みたいだ。

pip list コマンドで見てみると、Jinja2 のほかに MarkupSafe と言うパッケージがインストールされている。どうやら依存しているパッケージみたい。

^o^ > pip list
