can't use guzzle

[tacman]

With a very basic symfony app (based on the Symfony4.2 demo, all started plugins), I'm having difficult configuring the bundle.

I can install it, but can't install an adapter. The problem is httplug version, needs to allow version 2.

In HttpClientDiscovery.php line 27:
                                                                                                                                             
  No HTTPlug clients found. Make sure to install a package providing "php-http/client-implementation". Example: "php-http/guzzle6-adapter".

I was able to install guzzle6 with composer req php-http/guzzle6-adapter ^1, but better would be the ability to install it by default, with composer require php-http/guzzle6-adapter

The following worked for me:

composer require cspoo/swiftmailer-mailgun-bundle
composer require php-http/httplug-pack 1.1
