drupal cms do not install via composer

I had a similar issue installing a patch to project_browser yesterday. Full steps at https://www.drupal.org/project/project_browser/issues/3498901#comment-15... 🐛 Recipe description appears twice in modal Active

Error was

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

  Problem 1
    - Root composer.json requires drupal/drupal_cms_starter 1.x-dev -> satisfiable by drupal/drupal_cms_starter[1.x-dev].
    - drupal/drupal_cms_starter 1.x-dev requires drupal/project_browser ^2-alpha7 -> found drupal/project_browser[2.0.0-alpha7, 2.0.x-dev] but it conflicts with your root composer.json require (3498901-recipe-description-appears-dev).

I'm guessing you're having two different problems, both arising from the fact that you likely have made changes to your composer.json files that would not normally be the case in a regular Drupal project (or a regular Drupal CMS project, for that matter). The good news is it's easily fixed.

First, @volanar, your problem probably arises from not having the packages.drupal.org repository defined in your composer.json. Without that, you won't be able to download any Drupal modules at all. Here's documentation about that: https://www.drupal.org/docs/develop/using-composer/using-packagesdrupalorg → . Note that Drupal CMS does configure this repository by default, if you start with composer create-project drupal/cms:1.0.x-dev, or a zip file of that (1.0.0 will launch later today), which is the correct way to start a Drupal CMS project.

And @dunx, your problem is coming from you most likely having tested some merge request branch of Project Browser, so of course nothing that depends on a different tag of it will be able to come in, because Composer will find a conflict. You probably have something like "require": {"drupal/project_browser": "3498901-recipe-description-appears-dev"} in your composer.json somewhere. Remove that, along with anything in the repositories section that points to the Project Browser merge request fork, and try it again.

Tentatively closing because this is unlikely to be a Drupal CMS flaw, just misconfigured existing composer.json files. Feel free to reopen if you try my suggestions and continue to have problems.
