Had the same issue, quickest fix is to require "symfony/translation": "4.3.8" in your composer.json & run composer update

I received this error during installation. I don't seem to find composer.json anywhere. Am I missing anything? I'm using PHP 7.1

composer.json should be in the root directory of your laravel installation. So if your laravel app is in a folder called /Users/someuser/code/new-laravel you should find the composer.json file directly in that folder.

Why are you downgrading whole library if you can just downgrade an interface that causes an issue?
Add "symfony/translation-contracts": "^1.1.7" to your composer and run composer update, especially considering that symfony/translation clearly allows it in its composer json (if you check you will see ^1.1.6|^2 here https://packagist.org/packages/symfony/translation#v4.4.4).

This is the most viable solution and also the one that worked for me thanks !
