Problem 1
- lcobucci/jwt 4.3.0 requires ext-sodium * -> it is missing from your system. Install or enable PHP's sodium extension.
- league/oauth2-server-bundle v0.3.0 requires league/oauth2-server ^8.3 -> satisfiable by league/oauth2-server[8.4.1].
- ec-cube/api42 4.2.3 requires league/oauth2-server-bundle ^0.3 -> satisfiable by league/oauth2-server-bundle[v0.3.0].
- league/oauth2-server 8.4.1 requires lcobucci/jwt ^3.4.6 || ^4.0.4 -> satisfiable by lcobucci/jwt[4.3.0].
- ec-cube/api42 is locked to version 4.2.3 and an update of this package was not requested.

To enable extensions, verify that they are enabled in your .ini files:

You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-sodium` to temporarily ignore these required extensions.
[29.1MiB/2.10s] <warning>Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.</warning>
[27.6MiB/2.10s] You can also try re-running composer require with an explicit version constraint, e.g. "composer require ec-cube/CustomerGroup42:*" to figure out if any version is installable, or "composer require ec-cube/CustomerGroup42:^2.1" if you know which you need.

WEBで調べると
「WebAPIプラグインをアンインストールする」と記載があるのですが
「EC-CUBE Web API プラグイン(4.2系)」はインストールボタンが表示さあれ、インストールされていませんでした。

念のため上記のプラグインを一旦インストールして削除しようと思い、インストールをしました。「インストールが完了しました。」とメッセージは表示されるものの、プラグイン一覧画面には「インストール」ボタンが表示されます。

どうやってアンインストールするのでしょうか？
そもそもインストールされていないのでしょうか？
