composer Issue

Problem/Motivation

$ composer require 'drupal/simple_facebook_post:1.0.x-dev@dev'
./composer.json has been updated
Running composer update drupal/simple_facebook_post

Your requirements could not be resolved to an installable set of packages.

Problem 1
- joelbutcher/facebook-graph-sdk[6.0.0-beta1, ..., 6.x-dev] require psr/http-message ^1.0 -> found psr/http-message[1.0, 1.0.1, 1.1] but the package is fixed to 2.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- drupal/simple_facebook_post 1.0.x-dev is an alias of drupal/simple_facebook_post dev-1.0.x and thus requires it to be installed too.
- drupal/simple_facebook_post dev-1.0.x requires joelbutcher/facebook-graph-sdk ^6.0 -> satisfiable by joelbutcher/facebook-graph-sdk[6.0.0-beta1, ..., 6.x-dev].
- Root composer.json requires drupal/simple_facebook_post 1.0.x-dev@dev -> satisfiable by drupal/simple_facebook_post[1.0.x-dev (alias of dev-1.0.x)].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
