Unable to install/update

Hi @scbritton
I'm unable to replicate your issue from your message.
Be aware that only Drupal10+ are supported.

I ran:

composer create-project drupal/recommended-project PROJECTNAME
cd PROJECTNAME
ddev config
ddev composer require drush/drush
ddev drush site:install --account-name=admin --account-pass=admin -y
ddev composer require drupal/webform_booking
ddev drush en webform_booking

and everything seems to be working as expected.
(these commands require composer and ddev to be installed)

Hello,

I have the same problem on Drupal 11.1.2 with Drupal CMS.

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires drupal/webform_booking ^1.1 -> satisfiable by drupal/webform_booking[1.1.0, ..., 1.1.7].
    - drupal/webform_booking[1.1.0, ..., 1.1.7] require drupal/webform_ui * -> satisfiable by drupal/webform_ui[5.0.0, ..., 5.31.0, 6.0.0, ..., 6.2.9].
    - drupal/webform_ui[5.9.0, ..., 5.13.0] require drupal/core ^8.7.7 || ^9 -> found drupal/core[8.7.7, ..., 8.9.20, 9.0.0, ..., 9.5.11] but the package is fixed to 11.1.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - drupal/webform_ui[5.0.0, ..., 5.15.0] require drupal/core ^8 -> found drupal/core[8.0.0, ..., 8.9.20] but the package is fixed to 11.1.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - drupal/webform_ui[5.16.0, ..., 5.31.0] require drupal/core ^8.8 -> found drupal/core[8.8.0, ..., 8.9.20] but the package is fixed to 11.1.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - drupal/webform_ui[6.0.0, ..., 6.1.4] require drupal/core ^8.8 || ^9 -> found drupal/core[8.8.0, ..., 8.9.20, 9.0.0, ..., 9.5.11] but the package is fixed to 11.1.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - drupal/webform_ui[6.1.5, ..., 6.1.8] require drupal/core ^9.3 -> found drupal/core[9.3.0, ..., 9.5.11] but the package is fixed to 11.1.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

When trying
composer require drupal/webform_booking

the following version is installed:
drupal/webform_booking (1.0.13)

After that I download v1.1.7 from https://www.drupal.org/project/webform_booking/releases/1.1.7 → manually and it is working without any problems in Drupal CMS 11.1.2.

How can we solve the dependency problem?
Thank you.

I was able to force an install of this module by editing one of the yaml files. Unfortunately, I cannot remember which file I edited, where it was, or the edits I made at this exact moment in time. In reality, I'm so frustrated with Drupal as a whole that I'm about to throw in the towel on my project and go back to Wordpress.

Hi @drupalfan2, @scbritton
Looking at the composer error, I see that it fails to find a webform version that works.
There's no stable version of Webform for Drupal 11 yet, but I adjusted the webform requirement to be a little more generic:
"drupal/webform": "^6.0",
Try it out and let me know if it made any difference for you.

If the problem remains:

Drupal CMS is pretty new, and Drupal 11 overall still lacks stable releases for several contrib modules.
There are two possible 'workarounds'.
- In your main composer.json, change to:
"minimum-stability": "dev",
- Use mglaman composer-drupal-lenient
composer require mglaman/composer-drupal-lenient

Changing minimum-stability to "dev" from "stable" worked for me.
