pip install時のライブラリバージョンをyolkで確認する

Python

概要

あるライブラリが必要となり、最新バージョンっていくつだろう？となったときに使えるyolkライブラリ。

yolk：インストールされている Python パッケージの情報を取得し、PyPI (Python Package Index) で利用可能なパッケージを照会するための Python ツール。

yolk3k:オリジナルのyolkをフォークし、Python2サポートを維持しつつ、Python3のサポートを追加したもの。どのパッケージがアクティブか、ノンアクティブか、開発中かを確認でき、PyPIに問い合わせることで、より新しいバージョンが利用できるものを表示するなどの機能が追加されている。実行時のコマンドはyolkのまま。

インストール

以下のコマンドでyolk3kをインストールします。

pip install yolk3k

パッケージのバージョンおよびメタデータの表示

オプション「-V」でパッケージの最新バージョンが取得されます。

yolk -V [パッケージ名]

例えばDjangoであれば以下の通り。

> yolk -V Django
Django 4.1.4

また、オプション「-M」で確認すると、そのパッケージのメタデータをPyPIから取得して表示します。

> yolk -M Django

version: 4.1.4

======

Django is a high-level Python web framework that encourages rapid development
and clean, pragmatic design. Thanks for checking it out.

All documentation is in the "``docs``" directory and online at

Django
The web framework for perfectionists with deadlines.
docs.djangoproject.com
 If you're just getting started,
here's how we recommend you read the docs:

* First, read ``docs/intro/install.txt`` for instructions on installing Django.

* Next, work through the tutorials in order (``docs/intro/tutorial01.txt``,
  ``docs/intro/tutorial02.txt``, etc.).

* If you want to set up an actual deployment server, read
  ``docs/howto/deployment/index.txt`` for instructions.

* You'll probably want to read through the topical guides (in ``docs/topics``)
  next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific
  problems, and check out the reference (``docs/ref``) for gory details.

* See ``docs/README`` for instructions on building an HTML version of the docs.

Docs are updated rigorously. If you find any problems in the docs, or think
they should be clarified in any way, please take 30 seconds to fill out a
ticket here: https://code.djangoproject.com/newticket

To get more help:

* Join the ``#django`` channel on ``irc.libera.chat``. Lots of helpful people
  hang out there. See https://web.libera.chat if you're new to IRC.

* Join the django-users mailing list, or read the archives, at
  https://groups.google.com/group/django-users.

To contribute to Django:

* Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for
  information about getting involved.

To run Django's test suite:

* Follow the instructions in the "Unit tests" section of
  ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at
  https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests

yolkのヘルプ

その他のオプションについてはyolkのヘルプを参照

> yolk -h
usage: yolk [-h] [--version] [--debug] [-q] [-l] [-a] [-n] [-m] [-f FIELDS] [-d PKG_SPEC] [--entry-points MODULE]
            [--entry-map PACKAGE_NAME] [-C HOURS] [-D PKG_SPEC] [-F PKG_SPEC] [-H PKG_SPEC] [-I PYPI_INDEX] [-L HOURS]
            [-M PKG_SPEC] [-S SEARCH_SPEC <AND/OR SEARCH_SPEC>] [-T FILE_TYPE] [-U] [--upgrade] [--user] [-V PKG_SPEC]
            [pkg_spec]

positional arguments:
  pkg_spec

options:
  -h, --help            show this help message and exit

  such as packages installed with 'easy_install --multi-version'. PKG_SPEC can be either a package name or package
  name and version e.g. Paste==0.9

  -l, --list            list all Python packages installed by distutils or setuptools. Use PKG_SPEC to narrow results
  -a, --activated       list activated packages installed by distutils or setuptools. Use PKG_SPEC to narrow results
  -n, --non-activated   list non-activated packages installed by distutils or setuptools. Use PKG_SPEC to narrow
                        results
  -m, --metadata        show all metadata for packages installed by setuptools (use with -l -a or -n)
  -f FIELDS, --fields FIELDS
                        show specific metadata (comma-separated) fields; use with -m or -M
  -d PKG_SPEC, --depends PKG_SPEC
                        show dependencies for a package installed by setuptools if they are available
  --entry-points MODULE
                        list entry points for a module. e.g. --entry-points nose.plugins
