Переход на laravel 5.7 имеет ошибки npm

Question

Я обновил приложение laravel 5.6 до версии 5.7 с модификацией в моей строке composer.json 1:

...
"laravel/framework": "5.7.*",
...

и запущен

composer update

без ошибок в консоли.

Но после того, как я попытался обновить npm и получил ошибки:

$ npm update
npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.

$ php artisan --version

Как исправить эту ошибку?Что не так с моей текущей конфигурацией?

Спасибо!
