During installation of this module an error happens (cfr #2599042: Make D8 release of Visitors work again for details).

So I decided to uninstall the Visitors module, but I couldn't.

Instead I got this error in Drush:

Drupal\Core\Config\ImmutableConfigException: Can not delete immutable configuration visitors.config. Use \Drupal\Core\Config\ConfigFactoryInterface::getEditable() to retrieve a mutable configuration [error]
object in /var/www/drupal/core/lib/Drupal/Core/Config/ImmutableConfig.php:51

Now I cannot install or remove any new modules in my site. Please help.

@omix: you issue is similar to what is mentioned in #2599042: Make D8 release of Visitors work again, so I'm marking it like so.

Though I think it might help others if you can add some kind of update about if you somehow succeeded by now to get around this issue.

As per this comment in issue #2599042: Make D8 release of Visitors work again, a work around (for now) to this problem is to replace this line in visitors.install, which currently looks like so:

\Drupal::config('visitors.config')->delete();

It should be replace by a line that looks like so:

\Drupal::configFactory()->getEditable('visitor.config')->delete();
