Hello everyone,
Currently, I am encountering dependency issues while trying to upgrade the Drupal core to version 9. I have been following the steps from this page, by using the upgrade_status module, I have upgraded all modules that are compatible with Drupal 8. Only the modules that require Drupal 9 remain. I plan to upgrade them after I successfully upgrade the Drupal core.
And the commands I ran for upgrading Drupal core were:
composer require 'drupal/core-recommended:^9' 'drupal/core-composer-scaffold:^9' 'drupal/core-project-message:^9' --update-with-dependencies --no-update
composer update
However, I encountered the following error. I have tried modifying the corresponding package versions in the composer.json, but I still run into similar errors:
yucheng@yucheng:/var/www/ameb_composer$ composer update
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires drupal/context_active_trail ^3.0, found drupal/context_active_trail[dev-1.x, dev-2.x, 1.0.0-rc1, 1.0.0-rc2, 1.x-dev (alias of dev-1.x), 2.0.0-rc2, ..., 2.x-dev (alias of dev-2.x)] but it does not match the constraint.
Problem 2
- Root composer.json requires drupal/field_time ^2.0, found drupal/field_time[dev-1.0.x, 1.0.0-alpha1, ..., 1.0.x-dev (alias of dev-1.0.x)] but it does not match the constraint.
Problem 3
- Root composer.json requires drupal/scheduler ^3.0, found drupal/scheduler[dev-1.x, dev-2.x, 1.0.0-alpha1, ..., 1.x-dev (alias of dev-1.x), 2.0.0-alpha1, ..., 2.x-dev (alias of dev-2.x)] but it does not match the constraint.
Problem 4
- Root composer.json requires drupal/time_range ^3.0, found drupal/time_range[dev-1.x, 1.0.0, 1.1.0, 1.2.0, 1.x-dev (alias of dev-1.x), 2.0.1, 8.1.3, 9.0.0, 9.0.1, 9.0.2, 9.0.3] but it does not match the constraint.
Problem 5
- Root composer.json requires drupal/cms_content_sync ^3.0 -> satisfiable by drupal/cms_content_sync[3.0.0-beta1, ..., 3.0.x-dev].
- drupal/cms_content_sync[3.0.0-beta1, ..., 3.0.x-dev] require php >=8.0.0 -> your php version (7.4.33) does not satisfy that requirement.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
Here is my composer.json:
