I have installed WAMP Server for Postgresql and during the time of installation of Drupal (version 8), I got this error:

Drupal\Core\Config\UnmetDependenciesException: Configuration objects (block.block.bartik_search, core.entity_form_display.node.article.default, core.entity_form_display.node.page.default, rdf.mapping.comment.comment, rdf.mapping.node.article, rdf.mapping.node.page, rdf.mapping.taxonomy_term.tags) provided by standard have unmet dependencies in Drupal\Core\Config\UnmetDependenciesException::create() (line 89 of core\lib\Drupal\Core\Config\UnmetDependenciesException.php). Drupal\Core\Config\UnmetDependenciesException::create('standard', Array) Drupal\Core\Config\ConfigInstaller->checkConfigurationToInstall('module', 'standard') Drupal\Core\Extension\ModuleInstaller->install(Array, ) install_install_profile(Array) install_run_task(Array, Array) install_run_tasks(Array) install_drupal(Object)

How can I solve this?

  • You need to run: composer update in Drupal docroot to install missing dependencies. – kenorb Jan 15 '16 at 19:15

The UnmetDependenciesException is something you get when Drupal tries to install a configuration that depends on other modules/configuration which are missing.

You shouldn't see this error installing one of the standard install profiles. My hunch is that the source to your errors is PostgreSQL which is not fully supported by Drupal 8 at this time of writing.

See more in the issue queue: https://www.drupal.org/node/2157455 for running Drupal 8 on postgreSQL.
