composer requireで怒られた。[but these conflict with your requirements or minimum-stability.]

カーボン入れようとして、なんか怒られた

＄composer require nesbot/carbon
Using version ^2.14 for nesbot/carbon
./composer.json has been updated
Loading composer repositories with package information

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

Problem 1
    - laravel/framework v5.5.45 requires nesbot/carbon ^1.26.0 -> satisfiable by nesbot/carbon[1.26.0, 1.26.1, 1.26.2, 1.26.3, 1.26.4, 1.27.0, 1.28.0, 1.29.0, 1.29.1, 1.29.2, 1.30.0, 1.31.0, 1.31.1, 1.32.0, 1.33.0, 1.34.0, 1.34.1, 1.34.2, 1.34.3, 1.34.4, 1.35.0, 1.35.1, 1.36.0, 1.36.1, 1.36.2] but these conflict with your requirements or minimum-stability.
 (省略) 

原因

Ver2.14見つけけど、フレームワークは 1.26.0から1.36.2を要求してるから矛盾してるよ!!という事らしい

対応

バージョン指定してあげる

$ composer require nesbot/carbon:1.36.2
