Pythonの依存関係の管理とパッケージ化が簡単にできる「poetry」のインストール

Pythonの依存関係の管理とパッケージ化が簡単にできる「poetry」のインストールについて解説しています。

「poetry（https://python-poetry.org/,https://github.com/python-poetry/poetry）」は、Pythonプロジェクトの依存関係の宣言、管理、インストールが簡単に行えるライブラリです。

■Python

今回のPythonのバージョンは、「3.8.5」を使用しています。（Windows10）（pythonランチャーでの確認）

■poetryをインストールする

poetryをインストールを行いますが、今回はpipを経由してインストールを行うので、まずWindowsのコマンドプロンプトを起動します。

pip install poetry

起動後、上記のコマンドを入力し、Enterキーを押します。

なお、今回は、pythonランチャーを使用しており、Python Version 3.8.5にインストールを行うために、バージョンの切り替えを行います。

py -3.8 -m pip install poetry

切り替えるために、上記のコマンドを入力し、Enterキーを押します。

Enterキーを押すと、インストールが開始され、上記のように「Successfully installed」と表示されます。これが表示されれば、poetryが正常にインストールされたことになります。

なお、今回はpoetryのバージョン1.1.14をインストールしました。
