    }
}

I never understood composer log.

Can someone help me to decipher the error so I can see what I'm doing wrong?

Answer 1

I had similar issue today trying to install doctrine/doctrine-migrations-bundle. I will leave my answer here because, although the solution is simple, I have not found it elsewhere.

Just like we need doctrine/orm to have doctrine/doctrine-bundle, we need doctrine/migrations to have doctrine/doctrine-migrations-bundle.

So, include it also in your composer.json:

{
    "require": {
        "doctrine/migrations": "dev-master",
        "doctrine/doctrine-migrations-bundle": "dev-master"
    }
}
