Can't install latest version with composer

Additional information:

Tried to install calendar with Drupal 10.1 using composer version 2.5.1 (php 8.1) as follows:

composer require drupal/calendar:^1.0@BETA

Got the following message:

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

  Problem 1
    - Root composer.json requires drupal/calendar ^1.0@BETA -> satisfiable by drupal/calendar[1.0.0-beta1].
    - drupal/calendar 1.0.0-beta1 requires drupal/calendar_datetime * -> found drupal/calendar_datetime[dev-1.x, 1.0.0-alpha1, ..., 1.x-dev (alias of dev-1.x)] but it does not match your minimum-stability.

calendar_datetime is a submodule of calendar, and no separate project called drupal/calendar_datetime exists that I can locate. I dot not see an explicit dependency in the composer.json file for the project, the only place I can locate a dependency in the module code is in calendar.info.yml

In any case, this prevents installing the module with composer.

I have the same problem.

The command "composer require drupal/calendar:^1.0@beta" works for me if I changed the "minimum-stability" to "dev" instead of "stable" in the composer.json file.

"minimum-stability": "dev",
"prefer-stable": true,

10.1.6 and I wanted to confirm that I had the same issue here but simply altering my "minimum-stability" to be "dev" allows for the install.

"minimum-stability": "dev" worked for me. Thanks!

The error you're encountering is likely due to the fact that the minimum stability set in your Composer configuration is "stable". Since the module is still in development and a stable version hasn't been released yet, Composer is unable to resolve the dependencies properly.

To quickly address this error, you can adjust the minimum stability setting in your Composer configuration to "dev". This change will allow Composer to install modules that are in the development stage.

The problem still exists with the beta2

A beta should already be installable on test systems where they can be evaluated within a stable setting.

It is very strange.
I can install any dev version of other modules over my stable environment. I never have to set minimum stability to dev.
So I suspect there is something wrong with the setting of the submodule.

I don't want to change the minimum-stability of my project. What worked for me:

composer require drupal/calendar_datetime:^1.0@alpha && composer require 'drupal/calendar:^1.0@beta'

Thanks Jaypan.

Still not possible to install.

The command composer require drupal/calendar:^1.0@beta works for me.

Also add this in composer.json file.

"minimum-stability": "dev",
"prefer-stable": true,

Well, but why is this needed? I tested the software and it looks working for me. I may found some issues, but they all look not that dramatic that blocking the installation is needed.

Maybe the maintainer could explain why he think the module is so unready that it need to be so complicated. There are other alpha modules around that can be installed without changing the composer file manually.

I have not getting any issue when i have run composer require drupal/calendar:^1.0@beta command. (installed calendar module)

But we add “minimum-stability” because this configuration specifies the minimum stability level for installed packages.

I have *many* modules in alpha and beta versions installed and none was blocked by a minimum-stability blocker.

this worked for me. without changing "minimum-stability": "dev", in composer.json

$ composer require 'drupal/calendar_datetime:1.x-dev@dev' 'drupal/calendar:^1.0@beta'

I set the minimum-stability to dev and still get this when trying to install in a brand new Drupal 11 site.

  Problem 1
    - Root composer.json requires drupal/calendar ^1.0@beta -> satisfiable by drupal/calendar[1.0.0-beta1, 1.0.0-beta2].
    - drupal/calendar[1.0.0-beta1, ..., 1.0.0-beta2] require drupal/core ^9.4 || ^10 -> found drupal/core[9.4.0-alpha1, ..., 9.5.x-dev, 10.0.0-alpha1, ..., 10.4.x-dev] but the package is fixed to 11.0.5 (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.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
Composer [require drupal/calendar:^1.0@beta] failed, composer command failed: exit status 2. stderr=

I would like to pick this issue and resolve it.

Solved the installation error where it was a problem occuring due to minimum-stability.
This approach keeps the calendar_datetime submodule bundled with your module, and it works without the need for external repositories, ensuring that anyone installing the calendar module gets the required calendar_datetime submodule automatically and do not get the error for installing beta version either.

just a brief note in regards of the problem in #19 🐛 Can't install latest version with composer Active where the install in drupal 11 failed. the composer.json of the calendar module is missing version 11 in line 24:

https://git.drupalcode.org/project/calendar/-/blob/8.x-1.x/composer.json...

Just so nobody gets tripped up by this, I fixed the Drupal 11 composer mentioned in #19 issue in 🌱 Add Tests and enable gitlab-ci Active

There are lots of rough edges in the beta release. I am hoping to iron a bunch out and add some tests.
