La mise à jour de Composer ne signale aucun package à installer ou à mettre à jour

Question

• Version Laravel : 5.6.35
• Version PHP : 7.1.20
• Pilote et version de base de données : MySQL v5.5.61-0ubuntu0.14.04.1

Description :

Au moment où cette question a été posée, la dernière version de Laravel était la 5.6.37 - publiée il y a 2 jours, le 2 septembre 2018.

J'ai déjà un projet en cours de développement. Lorsque je cours composer update, j'obtiens toujours ce qui suit :

Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating optimized autoload files
> IlluminateFoundationComposerScripts::postAutoloadDump
> @php artisan package:discover
Discovered Package: fideloper/proxy
Discovered Package: laravel/tinker
Discovered Package: barryvdh/laravel-debugbar
Discovered Package: nunomaduro/collision
Package manifest generated successfully.

Cela n'a commencé qu'après avoir mis à jour mon projet Laravel vers la version 5.6.35.

Ce n'est pas le cas lorsque j'installe un nouveau projet Laravel. Sur une nouvelle installation, la dernière version de laravel est téléchargée, soit la 5.6.37.

Ce qui suit est mon fichier composer.json

    "prefer-stable": true
}

Étapes pour reproduire :

1. Il existe un projet Laravel <= 5.6.35
2. Exécuter la mise à jour du compositeur

Je ne sais pas où ni quoi j’ai dû faire une erreur.

J'ai essayé les méthodes suivantes

1. Courez composer dump-autoload &&composer update
2. Supprimez le fichier composer.lock et le répertoire vendor. Alors cours composer.lock 文件和 vendor 目录。然后运行 composer update

Mais impossible de mettre à jour mon projet vers Laravel version 5.6.37
