pythonのパッケージマネージャーといえばpipとかが一般的かと思いますが、poetryというものがnpmやyarnのように使えるものが出てきたとのことで試してみます
導入
curl -sSL https://install.python-poetry.org | python3 -
そうすると
Add `export PATH="/Users/hoge/.local/bin:$PATH"` to your shell configuration file.
Alternatively, you can call Poetry explicitly with `/Users/hoge/.local/bin/poetry`.
You can test that everything is set up by executing:
`poetry --version`
とパスを通せとのことなので、自分の環境では
.zshrc に
export PATH="/Users/hoge/.local/bin:$PATH"
を書き込んでおきました。
人によっては
.bashrc とか .bash_profileとかになるのかな
exec $SHELL -l
シェルを再起動してから
❯ poetry --version
Poetry (version 1.5.0)
パスが通ったぽいので準備OK
新規で初期化
❯ poetry new poetry-study
Created package poetry_study in poetry-study
treeコマンドで確認してみると
❯ tree -a
.
├── README.md
├── poetry_study
│ └── __init__.py
├── pyproject.toml
└── tests
└── __init__.py
2 directories, 4 files
こんな感じのファイル構成だった
既存ので初期化
poetry init
これで既存のディレクトリを初期化できるらしい
セットアップ
poetry install
パッケージの追加
poetry add numpy
としてみると
poetry.lockに
