I'm trying to install the Drupal PM (Project Management) module, which says to work with Drupal 10 and 11, on Drupal 11.1.
When I try to install it with Composer (composer require 'drupal/pm:4.1.x-dev@dev'), I get this error message.
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires drupal/pm 4.x-dev@dev -> satisfiable by drupal/pm[4.x-dev (alias of dev-4.x)].
- drupal/pm dev-4.x requires drupal/verf * -> satisfiable by drupal/verf[dev-1.x, dev-2.0.x, 1.0.0-beta1, ..., 1.x-dev, 2.0.0, 2.0.1, 2.0.2, 2.0.x-dev].
- drupal/verf[1.0.0-beta1, ..., 1.0.0-beta7] require drupal/core ~8.0 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev] but these were not loaded, likely because it conflicts with another require.
- drupal/verf 1.0.0 requires drupal/core ^8 || ^9 -> found drupal/core[8.0.0-beta6, ..., 8.9.x-dev, 9.0.0-alpha1, ..., 9.5.x-dev] but these were not loaded, likely because it conflicts with another require.
- drupal/verf[dev-1.x, dev-2.0.x, 1.x-dev, 2.0.0, ..., 2.0.x-dev] require drupal/core ^9 || ^10 -> found drupal/core[9.0.0-alpha1, ..., 9.5.x-dev, 10.0.0-alpha1, ..., 10.5.x-dev] but these were not loaded, likely because it conflicts with another require.
- drupal/pm 4.x-dev is an alias of drupal/pm dev-4.x and thus requires it to be installed too.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
Does anyone know how to fix this?
drupal/pmrequiresdrupal/verfwhich itself is not D11-compatible. See yourself: drupal.org/project/verf. Simply retry with a D10 project.drupal/verfin drupal.org/project/verf/issues/3435339 with drupal.org/docs/develop/using-composer/…
