I tried everything I could... I always get this message: - The requested package phppowertools/dom-query could not be found in any version, there may be a typo in the package name.
If you wondering my composer.json:
{
"repositories": [
{
"type": "vcs",
"url": "https://github.com/PHPPowertools/DOM-Query"
}
],
"require": {
"PHPPowertools/DOM-Query": "dev-master"
}
}
