I want to update Drupal Commerce to 8.x-2.0-beta7 from a clean, Composer-based installation of 8.x-2.0-beta6, following the documentation on http://docs.drupalcommerce.org/v2/getting-started/update.html.
I noticed that
composer update drupal/commerce --with-dependencies did not update drupal/core. This surprises me. Isn't drupal/core a dependency? Anyway, says it's white-listed so I then ran
composer update drupal/core.
Now I am hitting a problem with updates.
Fatal error: Cannot use Drupal\Console\Core\Bootstrap\DrupalConsoleCore as DrupalConsoleCore because the name is already in use in/pathto/commerce8/vendor/drupal/console/src/Bootstrap/Drupal.php on line 11
Fatal error: Cannot use Drupal\Console\Core\Bootstrap\DrupalConsoleCore as DrupalConsoleCore because the name is already in use in /pathto/commerce8/vendor/drupal/console/src/Bootstrap/Drupal.php on line 11
I have since run update.php, but the Composer errors persist.
I am learning about Composer, and I don't know yet anything about Drupal Console.
What am I doing wrong?
