Any help will be appreciated!

Thanks.

Answer 1

it's issue because some of your package version is not supporting new laravel version 5.4

For example

"cartalyst/stripe-laravel": "5.0.*"

cartalyst/stripe-laravel version 5.0.1 only compatible with laravel 5.3 or lower so it's not support your new laravel.

Now you have two method to update your laravel

1. you can remove "cartalyst/stripe-laravel": "5.0.*" from your package json and just add like composer require cartalyst/stripe-laravel this command add your compatible version in your system
2. or just find manually compatible version of cartalyst/stripe-laravel and replace in your package json form here cartakyst.stripe-laravel
