[memo] pythonのパッケージ管理ryeを使ってみた（スクラップの転記）

ライと読むらしい（たぶん）

インストール

curl -sSf https://rye-up.com/get | bash

homebrewもありました。
https://formulae.brew.sh/formula/rye

パスを通す

echo 'source "$HOME/.rye/env"' >> ~/.zshrc
source ~/.zshrc

新規プロジェクトの作成

rye init test-project

プロジェクトはこんな感じ

$ tree test-project 
test-project
├── README.md
├── pyproject.toml
└── src
    └── test_project
        └── __init__.py

3 directories, 3 files

pyproject.tomlでPythonプロジェクトのビルドシステムの要件や依存関係を定義します。

pythonのバージョンを指定する

rye pin 3.11

バージョンファイルが作成されます。

仮想環境を作成

rye sync

ここでエラー発生

ここ <ExportEntry hello = test:None []> helloというエントリーポイントがないよと言っている。

pyproject.toml

[project.scripts]
hello = "test-project:hello"

ディレクトリ

$ tree src 
src
└── test_project
    └── __init__.py

ディレクトリ名が違うせいですね。（なんでや）

pyproject.tomlを修正

[project.scripts]
hello = "test_project:hello"

試してみる

$ rye run hello
Hello from test-project!

無事動きました。

ライブラリの追加

rye add openai

で同期する

rye sync

おまけ

Dockerなどでryeは入れたくないけど、pip installしたい場合は以下のような形で requirements.lock を書き換えてあげましょう。

FROM python:3.12.0-slim as builder

WORKDIR /build

COPY requirements.lock ./

RUN sed '/-e/d' requirements.lock > requirements.txt && \
    pip install --user -r requirements.txt
