Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Installation failed, reverting ./composer.json to its original content.`

Based on this output alone I can't figure out what's the problem, could someone please point me in the right direction? Thanks!

I had much the same with composer require drupal/console:^1.0@RC just now.

I have the same problem, I created my setup with Acquia BLT, and for some reason I have symfony/config 3.2.9 installed.

[kviolka]

https://github.com/hechoendrupal/drupal-console-core/blob/master/composer.json requires symfony/console < 3.0

[jmolivas]

@kviolka Are you using lightning distro? This may help => https://drupalconsole.com/articles/add-drupalconsole-to-a-project-using-acquia-lightning-distribution

Same issue here. Could not install drupal-console on drupal 8.4.x

I can verify that 8.4.x results in similar issues, but 8.3.x works as expected.

To note:
This packaged is a requirement in https://github.com/drupal-composer/drupal-project
And to use drupal/core : ~8.4 you need to use drush/drush: "~9.0", maybe you can check with the drush package as well since Drush uses the latest version of dependencies from Symfony and Drupal console's dependencies (at the moment) are set to v2.8* max.
