eclipse2023(Python Windows 64bit版)にて、一部外部ライブラリが正常にインストールできない

[hana2sei]

eclipse2023(Python Windows 64bit版)にて、外部ライブラリpsycopg2のインストールに失敗します。 matplotlibやscikit-learnは正常にインストールできます。 不思議なのが、eclipseの2022や2021では正常にインストールできるという点です。2023でなにか内部仕様に変更があったのでしょうか？

Pleiades All in One の付属 Python バージョン 2022 -> 3.11 2023 -> 3.12

psycopg2 は現在 Python 3.12 対応中のようです。 https://github.com/psycopg/psycopg2/issues/1628

上記対応を待つか、python/3 ディレクトリを 2022 版のものに置き換えるかなどの対応が考えられます。

[hana2sei]

迅速な対応、および対応案のご提示ありがとうございます。 ライブラリ側の対応完了を待ちたいと思います。

[cypher256]

対応済みの psycopg2 がリリース済みのようなので、クローズします。
