Now, a good amount of modules do not yet have a stable version, for example, webform. composer require drupal/webform says:

Could not find package drupal/webform at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability

If I try composer require --minimum-stability=beta drupal/webform, I get:

The "--minimum-stability" option does not exist.

drush dl gives:

This codebase is assembled with Composer instead of Drush. Use composer update and composer require instead of drush pm-updatecode and drush pm-download.

Note that due to the special versioning of Drupal this is not a generic composer question but a Drupal specific one. Ie. webform today is 8.x-5.0-beta12, how do I install the latest in the 8.x-5.0 series...? Now, composer doesn't understand or use 8.x-5.0 but uses somethting else, but what and how does that work for betas? This needs documentation somewhere because it currently does not exist. I would be the happiest person if this didn't need an answer, but alas, despite having perfectly fine working tools to build sites, with Drupal 8 we need to use composer and most modules are in beta.

This installs the latest beta-12 for me:

composer require drupal/webform:5.0.*@dev

You need to do a bit of translation from the Drupal version number. From Using Composer to manage Drupal site dependencies:

Specifying a version you can specify a version from the command line with:

 $ composer require drupal/<modulename>:<version> 

For example:

 $ composer require drupal/ctools:3.0.0-alpha26
 $ composer require drupal/token:1.x-dev 

In these examples, the composer version 3.0.0-alpha26 maps to the drupal.org version 8.x-3.0-alpha26 and 1.x-dev maps to 8.x-1.x branch on drupal.org.

If you specify a branch, such as 1.x you must add -dev to the end of the version.

Hence for Webform, 8.5 becomes 5.0.x, and that's what you need to use to identify the package correctly.

  • This doesn't work. composer require 'drupal/bricks:2.0.*@dev' goes Downgrading drupal/bricks (2.0.2-beta1 => 2.0.1) , I just released 2.0.2-beta2. Sep 24, 2021 at 8:47
  • Works fine for me and plenty of others, check the rest of your configuration

The reason this doesn't work because the "stable preference" of composer is not a preference but a hard choice which you can not override with anything except specifying an exact version.

If you have "prefer-stable": true, in your composer.json then the only way to install a beta module is composer require 'drupal/bricks:2.0.2-beta2'. Neither 2.0.*@dev nor anything else will work except that.

Switching that setting off with composer config prefer-stable false is possible but it might affect other modules.

You can check why composer refuses to do what you tell it to do -- because of course it does -- with composer why-not drupal/bricks:2.0.2-beta2.
