The package is not available in a stable-enough version

Question

Following situation:

• app requires andig/dbcopy in dev version: composer require andig/dbcopy:dev-master

• andig/dbcopy requires symfony/consolein dev version (due to a bug in 2.5):

  "require": {
      "doctrine/dbal": "2.4.*",
      "symfony/console": "2.6.*@dev"
  },
  

Now, when adding andig/dbcopy to the app using composer require, composer complains about stability:

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

  Problem 1
    - Installation request for andig/dbcopy dev-master -> satisfiable by andig/dbcopy[dev-master].
    - andig/dbcopy dev-master requires symfony/console 2.6.*@dev -> no matching package found.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://groups.google.com/d/topic/composer-dev/_g3ASeIFlrc/discussion> for more details.

No minimum-stability settings have been defined, the app already has a dependency on a dev-master package.

I've read https://groups.google.com/forum/#!topic/composer-dev/_g3ASeIFlrc/discussion but I'm still confused as to why composer fails to install even though

• all stability settings are explicitly defined and
• the app itself already has another dependency on "dev-master" which works?

Answer 1

Just put:

"symfony/console": "2.6.*@dev"

in your main composer.json. You must override stability requirement directly.
