Php – Composer – The requested package exists as but these are rejected by your constraint

I found the proper solution.

Here's what I did.

First:

I removed the minimum-stability field inside the composer.json of my packages A and B; For the minumum-stability is a root-only field. As, described in this [link] https://getcomposer.org/doc/04-schema.md#minimum-stability).

But the real solution was, as I was working with my own private package, I was using bitbucket to host the two packages, pointing the repos in the "repositories" field inside my composer.json inside of the root composer and the packageB composer.

And that is what was wrong.

As described in this link, the composer's root package has to include the link of all the repos inside the repositories field.

Being just like so:

The root package short version of my composer.json

{
  "require": {      
    "packageB/packageB": "dev-master"
  },
  "repositories": [
    {
      "type": "vcs",
      "url":  "git@bitbucket.org:packageB/packageB.git"
    },
    {
      "type": "vcs",
      "url":  "git@bitbucket.org:packageA/packageA.git"
    }
  ],
  "minimum-stability": "dev"
}

The packageA short version of my composer.json

{
    "require": {      

    }
}

The packageB short version of my composer.json

{
  "require": {      
    "packageA/packageA": "dev-master"
  }
}

Hope it works, because it worked for me. Peace out!

To get the current memory_limit value, run:

php -r "echo ini_get('memory_limit').PHP_EOL;"

Try increasing the limit in your php.ini file (ex. /etc/php5/cli/php.ini for Debian-like systems):

; Use -1 for unlimited or define an explicit value like 2G
memory_limit = -1

Or, you can increase the limit with a command-line argument:

php -d memory_limit=-1 composer.phar require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

To get loaded php.ini files location try:

php --ini

Another quick solution:

php composer.phar COMPOSER_MEMORY_LIMIT=-1 require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

Or just:

COMPOSER_MEMORY_LIMIT=-1 composer require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle
