composer will no longer update

Question

Here is my composer.json:

    {
        "name": "laravel/laravel",
        "description": "The Laravel Framework.",
        "keywords": ["framework", "laravel"],
        "license": "MIT",
        "require": {
                "laravel/framework": "4.2.*",
                "greggilbert/recaptcha": "dev-master",
                "way/generators": "~2.0"
        },
        "autoload": {
                "classmap": [
                        "app/commands",
                        "app/controllers",
                        "app/models",
                        "app/database/migrations",
                        "app/database/seeds",
                        "app/tests/TestCase.php"
                ],
                "psr-0": {
                    "MSHLibrary": "app/"
                }
        },
        "scripts": {
                "post-install-cmd": [
                        "php artisan clear-compiled",
                        "php artisan optimize"
                ],
                "post-update-cmd": [
                        "php artisan clear-compiled",
                        "php artisan optimize"
                ],
                "post-create-project-cmd": [
                        "php artisan key:generate"
                ]
        },
        "config": {
                "preferred-install": "dist"
        },
        "minimum-stability": "stable",
        "require-dev": {
                "fzaninotto/faker": "~1.4"
        }
}

However when I run composer update (yes I have run composer self-update) I get:

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Any ideas?

Answer 1

You appear to be getting the dev-master version of greggilbert/recaptcha, but according to its README, it's only to be used for Laravel 5 projects.

To fix this, try 1.* releases instead; they're suited for Laravel 4:

"greggilbert/recaptcha": "1.*",
