I need to install https://github.com/PHPGangsta/GoogleAuthenticator but if I run composer require "PHPGangsta/GoogleAuthenticator:1.0.1" I get an error:
Your requirements could not be resolved to an installable set of packages.
Problem 1 - The requested package phpgangsta/googleauthenticator 1.0.1 exists as phpgangsta/googleauthenticator[dev-master] but these are rejected by your constraint.
Here is composer.json where is only restriction for PHP version.
{
"require": {
"php": ">=5.6.1",
"league/oauth1-client": "^1.7",
"mongodb/mongodb": "^1.3",
"ruflin/elastica": "^5.3"
}
}
Can somebody explain me please what is the problem?
