Install dependency (doctrine/dbal) on composer laravel

I am trying to execute a migration to rename some columns and I got an exception.

As I read on the documentation I have to add the doctrine/dbal dependency to my composer.json file. How do I do that? Which is the correct composer.json file. I have many in my application. Is the one that is on the same level as the folders app,bootstrap, public and vendor.

If so how do I add that dependency. Do I have to download anything?

By the way im using easyphp, not wamp!

Edit 1

After doing that the console throws this error

1) To install dependency , run this command

composer require doctrine/dbal

2) For 'git' is not recognized error, either you don't have git installed or the PATH is not added in the environment variables.

Install git for windows.


This should be the answer. It auto adds it with the correct version to composer.json

To add this dependency open the composer.json at the root of your project (in the same level as app, public etc.) and in the require section add the doctrine/dbal package like:

"require": {
    "laravel/framework": "4.1.*",
    "doctrine/dbal": "v2.4.2"
},

Save the file and run composer update

Edit

You probably installed git with the default settings and it's not in your PATH env.

Open Git Bash (it was installed with git - you will find it in your programs) and do composer update. By the way it's far better that windows command prompt.


Won't composer update cause updates to every package in composer.json and overwriting composer.lock? I prefer using only composer install to be safe because I have experienced things going terribly wrong after blindly calling composer update.
@JustAMartin If you explicitly set the version numbers in composer.json, then those won't/shouldn't update. If you set it like above (4.1.*) then that will update to 4.1.9 and stop updating. if you just use a version number like (2.4.2) then it should never update (but will install if not already) This is in theory, I've never had a reason to worry since I'm using the latest version of everything atm, but in the past I know there were major changes between versions so I can understand where problems would arise.
composer require is the right answer here, so you won't have to fiddle around with version numbers/updates
After i install, when i run php artisan migrate its showing error In AbstractPlatform.php line 423: Unknown database type enum requested, Doctrine\DBAL\Platforms\MySqlPlatform may not support it.

If you are getting error while running migration try this

composer require doctrine/dbal:2.*
