Add DrupalConsole to a project using Acquia Lightning distribution

Lightning is a base distribution maintained by Acquia. In this short blog post you will learn how to fix the dependency conflicts when trying to add DrupalConsole to a project using the Lightning distribution.

Lightning distribution repository at github

Link of the reported issue between dependencies of the Lightning distribution and DrupalConsole

Download Lightning distribution

[gist-embed data-gist-id="c5c6cda0640555becc618d9e64690560" data-gist-file="install-lightning.bash" data-gist-hide-footer="true" data-gist-hide-line-numbers="true" data-gist-show-loading="false"]

As you can read we are passing the --no-install flag, this will skip installation of the package dependencies, and it is required to avoid the conflict between dependencies.

Download DrupalConsole

According to project instructions at readme file.

[gist-embed data-gist-id="c5c6cda0640555becc618d9e64690560" data-gist-file="install-drupal-console.bash" data-gist-hide-footer="true" data-gist-hide-line-numbers="true" data-gist-show-loading="false"]

This command will add the DrupalConsole dependency to the composer.json file and then resolve and download Lightning + DrupalConsole.

Download DrupalConsole on a current project based on Lightning distribution

If you already have a project using the Lightning distribution then you can download DrupalConsole by executing

[gist-embed data-gist-id="c5c6cda0640555becc618d9e64690560" data-gist-file="install-drupal-console-no-update.bash" data-gist-hide-footer="true" data-gist-hide-line-numbers="true" data-gist-show-loading="false"]

By using the --no-update flag we are disabling the automatic update of the dependencies.

Finally just execute the following composer command to update project dependencies.

[gist-embed data-gist-id="c5c6cda0640555becc618d9e64690560" data-gist-file="composer-update.bash" data-gist-hide-footer="true" data-gist-hide-line-numbers="true" data-gist-show-loading="false"]

Thanks to Adam Balsama for this recommendation at the issue.
