I used composer create-project drupal-composer/drupal-project and have happily been using composer install composer require and composer update to keep my development system up-to-date and moving it around different development machines.

However, the upgrade to Drupal 8.1.0 from 8.0.6 was clumsier that I'd expected. Is there a slicker way of upgrading all the symfony dependencies than this?

composer require drupal/entity:8.1.0-alpha2 drupal/core:8.1.0 \
    symfony/process:~2.8 symfony/console:~2.8 symfony/event-dispatcher:~2.8 \
    symfony/yaml:~2.8 symfony/translation:~2.8 symfony/validator:~2.8 \
    symfony/serializer:~2.8 symfony/routing:~2.8  symfony/http-foundation:~2.8 \
    symfony/http-kernel:~2.8 symfony/dependency-injection:~2.8 \

BTW This current (25 April) sole answer to the duplicate question didn't work for me. e.g. - drupal/entity 8.0.1 requires drupal/system <8.1.0 -> satisfiable by drupal/core[8.0.6, 8.0.x-dev]. caused Your requirements could not be resolved to an installable set of packages. So I had to require each of 8.1.0's dependencies in turn just the same as without the --update-with-dependencies option. Painful.

  • I think so too. Since there was no response and the question is very similar, I voted to close as duplicate. There's little benefit to repeat the answer here. And in this case, drupal-project is used, so my suggestion there should work fine.

  • Yes the referenced question looks to be similar. Just haven't had a chance to try the solution.

  • The answer to the duplicate question does work for me now. Apologies for dissing the answer. Can't explain what's changed to make it work as advised.
