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.

  • The problem actually is github.com/composer/composer/issues/6426 this bug: git, make and vagrant all does something sensible when running in a subdir (git and vagrant goes up the tree, make just gives up) while composer creates an empty composer.json and doesn't display any error messages. facepalm Jun 25 '17 at 23:00
