[FIXED] requires ext-fileinfo. How do I add that into my composer.json file?

Issue

I am trying to install intervention/image. After running the composer update, I get:

This is my composer file:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "require": {
        "laravel/framework": "4.1.*",
        "intervention/image": "2.*"
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
    },
    "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"
}

Solution

Nothing to do with your composer.json.

You need to install & enable FileInfo PHP extension, which is installed by default starting with PHP 5.3.0. Versions prior to 5.3+ may use the discontinued PECL extension.

To enable FileInfo extension, you need to edit your php.ini and change a single line.

1. Locate the line:

   ;extension=php_fileinfo.dll
   

2. Remove the starting comment:

   extension=php_fileinfo.dll
   

---

To find out where your php.ini is located, you can run the following command from a terminal:

$ php --ini

and search for "Loaded Configuration File".

Please note that the PHP CLI can load a different php.ini file than the web, so don't rely on the path provided in phpinfo(). Run the command specified above in a terminal to find out the file loaded by PHP CLI.
