Chyba při stahování sandboxu composerem – nette/bootstrap

Ahoj,

děje se mi taková zvláštní věc. V composer.json mám toto:

{
	"require": {
		"php": ">=5.4.0",
		"nette/application": "~2.3",
		"nette/bootstrap": "~2.3",
		"nette/caching": "~2.3",
		"nette/component-model": "~2.3",
		"nette/database": "~2.3",
		"nette/di": "~2.3",
		"nette/finder": "~2.3",
		"nette/forms": "~2.3",
		"nette/http": "~2.3",
		"nette/mail": "~2.3",
		"nette/neon": "~2.3",
		"nette/php-generator": "~2.3",
		"nette/reflection": "~2.3",
		"nette/robot-loader": "~2.3",
		"nette/safe-stream": "~2.3",
		"nette/security": "~2.3",
		"nette/tokenizer": "~2.3",
		"nette/utils": "~2.3",
		"latte/latte": "~2.3",
		"tracy/tracy": "~2.3",
		"dg/adminer-custom": "~1.0"
	}
}

a po spuštěni composer.phar install se mi vypíše tato hláška:

[RuntimeException]
  Could not load package nette/bootstrap in http://packagist.org: [UnexpectedValueException] Could not parse version constraint >=2.2.1 <2.3: Invalid version string "2
  .2.1 <2.3"

Hlásí to problém s verzí nette\bootstrap, ovšem verzi 2.2, já zde chci verzi 2.3. Myslím, že fungovat by to mělo.
