【IT】poetryの導入

2023年1月10日 22:13

皆さま
こんにちは

Djagoフレームワークで主に使っている
Pythonのパッケージ管理にpipを使っております。

今回は、別のパッケージ管理ツールの「poetry」
を導入します。

最初に、テスト用のユーザ（ユーザ名を'testpoetry'とします）
を作成し、pyenvを導入します。

$ sudo su -
[sudo] lmf のパスワード:
＃ useradd -m -s /bin/bash testpoetry
＃ passwd testpoetry
新しいパスワード:
新しいパスワードを再入力してください:
passwd: パスワードは正しく更新されました

＃ usermod -aG docker testpoetry
＃ usermod -aG sudo testpoetry
＃ id testpoetry
uid=1008(testpoetry) gid=1009(testpoetry) groups=1009(testpoetry),27(sudo),998(docker)
＃ su - testpoetry
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.
＃ su - testpoetry

$ cd ~/
$ cp -p .bashrc .bashrc_orig
$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(pyenv init -)"' >> ~/.bashrc
$ source ~/.bashrc

poetryを導入します。

$ curl -sSL https://install.python-poetry.org | python3 -
Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

/home/testpoetry/.local/bin

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Installing Poetry (1.3.1): Creating environment
Installing Poetry (1.3.1): Done

Poetry (1.3.1) is installed now. Great!

To get started you need Poetry's bin directory (/home/testpoetry/.local/bin) in your `PATH`
environment variable.

Add `export PATH="/home/testpoetry/.local/bin:$PATH"` to your shell configuration file.

Alternatively, you can call Poetry explicitly with `/home/testpoetry/.local/bin/poetry`.

You can test that everything is set up by executing:

`poetry --version`

.bashrcにPATHに’$HOME/.local/bin’を追記します。

export PYENV_ROOT="$HOME/.pyenv"
##export PATH="$PYENV_ROOT/bin:$PATH"
export PATH="$PYENV_ROOT/bin:$PATH:$HOME/.local/bin"
eval "$(pyenv init -)"

利用できるか確認します。

$ poetry --version
Poetry (version 1.3.1)

テスト用の環境を作成します。

$ mkdir testsend2
$ cd testsend2/
$ poetry init

This command will guide you through creating your pyproject.toml config.

Package name [testsend2]:
Version [0.1.0]:
Description []:
Author [None, n to skip]:  n
License []:
Compatible Python versions [^3.11]:

Would you like to define your main dependencies interactively? (yes/no) [yes]
You can specify a package in the following forms:
  - A single name (requests): this will search for matches on PyPI
  - A name and a constraint (requests@^2.23.0)
  - A git url (git+https://github.com/python-poetry/poetry.git)
  - A git url with a revision (git+https://github.com/python-poetry/poetry.git#develop)
  - A file path (../my-package/my-package.whl)
  - A directory (../my-package/)
  - A url (https://example.com/packages/my-package-0.1.0.tar.gz)

Package to add or search for (leave blank to skip):

次にpoetryのvirtualenvをVScodeの認識させます。
（VScodeでDjangoのファイルを開いた時に波線で警告とならないように）

$ poetry --version
Poetry (version 1.3.1)

$ poetry config virtualenvs.in-project true --local

$ poetry env remove 3.xx.y
 　先にpoetry shellを実行して
　　　poetry env use 3.xx.yを実行している場合のみ実施
　　　既存のvirtualenvを削除します。
　
$ poetry install

仮想環境へ入って任意のモジュール（以下の例はDjango)を導入します。

$ source .venv/bin/activate
(testsend2-py3.11) testsend2$ poetry add django@3.2.7

  • Installing django (3.2.7)

$ django-admin startproject config .
$ ls
config  manage.py  poetry.lock  poetry.toml  pyproject.toml

無事導入出来ました。

途中で以下のエラーなる場合がありますが、メッセージに従い対応すると
復旧しました。
keyringrc.cfgの場所が問題となるようです。

$ poetry add django@3.2.7

Failed to create the collection: Prompt dismissed..
　
この場合は、keyring --disable　を入力すると直るとGit上にありますので入力します。
ここで直る場合もあります。

$ keyring --disable
$ poetry add django@3.2.7

Keyring config exists only in the old location /home/testpoetry/.local/share/python_keyring/keyringrc.cfg and should be moved to /home/testpoetry/.config/python_keyring/keyringrc.cfg to work with this version of keyring.
 
ここで違うエラーとなりますがメッセージに従い対応策を実施します。
$ mkdir /home/testpoetry2/.config/python_keyring/
$ cd /home/testpoetry2/.local/share/python_keyring/
$ mv keyringrc.cfg /home/testpoetry2/.config/python_keyring/
 
$  poetry add django@3.2.7
