    - laravel/ui[v1.2.0, ..., 1.x-dev] require illuminate/support ~5.8|^6.0 -> satisfiable by illuminate/support[v5.8.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev].
    - Only one of these can be installed: illuminate/support[v5.4.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev], laravel/framework[v7.0.0, ..., 7.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
    - Root composer.json requires laravel/framework ^7.0 -> satisfiable by laravel/framework[v7.0.0, ..., 7.x-dev].
    - Root composer.json requires laravel/ui ^1.2 -> satisfiable by laravel/ui[v1.2.0, v1.3.0, 1.x-dev].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
PS C:\Users\riiic\cookingDiary> yum install --enablerepo=remi,remi-php70 php php-devel php-mbstring php-pdo php-gd

補足情報（FW/ツールのバージョンなど）

Composer version 2.0.1
PHP 7.3.9

Answer 1

laravel/uiをv2にする。
composer.jsonのrequire-devでインストールしていたならrequireに移動させる。

教えていただきありがとうございます！
requireにlaravel/uiは移動してありましたが、"laravel/ui": "^1.2"になっていたので
"laravel/ui": "^2.1"を設定したら composer updateコマンドが通りました。
