laravel/breezeをインストールしようとしたらエラーが出た

概要

• composerを用いてbreezeをインストールしようとしたらエラーが出たので筆者の場合の解消方法をまとめる。

エラー

• どうやらバージョンがコンフリクトしている模様

$ composer require laravel/breeze

Deprecated: PHP Startup: Use of mbstring.internal_encoding is deprecated in Unknown on line 0
Using version ^1.11 for laravel/breeze
./composer.json has been updated

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/breeze[v1.11.2, ..., 1.x-dev] require illuminate/console ^9.21 -> found illuminate/console[v9.21.0, ..., 9.x-dev] but these were not loaded, likely because it conflicts with another require.
    - laravel/framework is locked to version v9.1.0 and an update of this package was not requested.
    - laravel/breeze[v1.11.0, ..., v1.11.1] conflict with laravel/framework <9.19.0.
    - Root composer.json requires laravel/breeze ^1.11 -> satisfiable by laravel/breeze[v1.11.0, v1.11.1, v1.11.2, 1.x-dev].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require laravel/breeze:*" to figure out if any version is installable, or "composer require laravel/breeze:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

解決までの経緯

• 下記を実行してcomposerのupdateを実施した。

  composer update
  

• 再度下記を実行したところ問題なくbreezeがインストールできた。

  composer require laravel/breeze --dev
