I am upgrading a project from laravel 5.3 to laravel 5.4 and go through every documentation available online. everything works fine, but when I do a composer update I get the following error. [error message]
Download composer repositories with package information Updating dependencies (including require-dev)

The composer.json file looks like this:
{ "name": "laravel/laravel", "description": "The Laravel Framework.", "keywords": ["framework", "laravel"], "license": "MIT", "type": "project", "minimum-stability": "dev", "prefer-stable": true, "require": { "php": ">=5.6.4", "toin0u/geocoder-laravel": "@stable", "laravel/framework": "5.4.*", "illuminate/support": "5.4.x", "illuminate/console": "5.4.x", "symfony/process": "~3.2", "barryvdh/laravel-async-queue": "0.4.x", "laravelcollective/html": "5.4.x-dev" }, "require-dev": { "fzaninotto/faker": "~1.4", "mockery/mockery": "0.9.*", "phpunit/phpunit": "~5.7", "symfony/css-selector": "3.1.*", "symfony/dom-crawler": "3.1.*", "barryvdh/laravel-debugbar": "^2.1" }, "autoload": { "classmap": [ "database", "app/Models", "database/migrations", "database/seeds", "app/libraries" ], "psr-4": { "App\\": "app/" } }, "extra": { "branch-alias": { "dev-master": "0.6-dev" } }, "autoload-dev": { "classmap": [ "tests/TestCase.php" ] }, "scripts": { "post-root-package-install": [ "php -r \"file_exists('.env') || copy('.env.example', '.env');\"" ], "post-create-project-cmd": [ "php artisan key:generate" ], "post-install-cmd": [ "Illuminate\\Foundation\\ComposerScripts::postInstall", "php artisan optimize" ], "post-update-cmd": [ "Illuminate\\Foundation\\ComposerScripts::postUpdate", "php artisan optimize" ] }, "config": { "preferred-install": "dist" } }
I did a composer install before updating it to download all dependencies. To fix another error, I made a small change in the requirement of the composer.lock file

I cannot remove the above error by stating that your requirements cannot be resolved. Please help me, thanks in advance.
