複数人で作業しており、その際に「データ移行プラグイン」をインストールしました。

ソースはgitで共有し、データベースはカラム追加・プラグイン追加の際に 新しいデータベースを所有している人のデータベースをもらい、入れなおして作業しておりました。

作業中にインストールしたはずの
「データ移行プラグイン」
にインストールボタンが表示され、インストールされていない状態？
になってるのに気が付きました。

キャッシュを削除してインストールしなおしたところ、
インストールボタンが表示されたままで、有効化にも無効化にもなっていません。

解消方法はありますでしょうか？

インストール時のログは下記になります。

返信ありがとうございます。

コマンドラインからインストールと有効化を試してみました。

インストールは 特に問題なさそうでしたが、
有効化が、「 [ERROR] Plugin `DataMigration4` is not found.」
と表示され、有効化できませんでした。

解消方法ありますでしょうか？

エラーメッセージからわかるとおり、プラグインが正常にインストールされていないようです。

一度、プラグインを強制的に削除してやり直してみてください。

◆プラグインを強制削除

・ dtb_plugin のプラグインの対象プラグインのレコードを削除する。

DELETE FROM `dtb_plugin` WHERE `code` = 'DataMigration4';

・ app/Plugin 配下の対象プラグインのディレクトリを削除する。

$ rm -rf app/Plugin/DataMigration4

・公開ディレクトリ直下の composer.json を開き、対象プラグインのコードを大文字小文字の区別なしで検索して、記述があれば削除する。

・プロキシを再生成する。
　念のため、 app/proxy/entity/src/Eccube/Entity 配下のファイルをバックアップしておく。

$ rm -f app/proxy/entity/src/Eccube/Entity/*.php
$ composer dump-autoload
$ php bin/console eccube:generate:proxies

・キャッシュを削除する。

$ php bin/console cache:clear --no-warmup
