Using version ^3.1 for laravel/ui
./composer.json has been updated
Running composer update laravel/ui

Problem 1
- laravel/ui[v3.1.0, ..., 3.x-dev] require illuminate/console ^8.0 -> found illuminate/console[v8.0.0, ..., 8.x-dev] but it conflicts with another require.
- Root composer.json requires laravel/ui ^3.1 -> satisfiable by laravel/ui[v3.1.0, 3.x-dev].
Installation failed, reverting ./composer.json and ./composer.lock to their original content.■解決方法
バージョンを合わせてインストールしてやれば良い
composer require laravel/ui 2.*Laravel6の場合は、”1.*”にしてやれば良い？ ※未確認
composer require laravel/ui 1.*
