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://getcomposer.org/doc/04-schema.md#minimum-stability for more details.
• It's a private package and you forgot to add a custom repository to find it

What command did you run exactly before you got this error? In what environment? Mac, Windows, Raspberry Pi?

I think the problem is that the virtual branch 1.3.x-dev on behat/mink-selenium2-driver doesn't exist anymore because 1.4.0 was released.

I ran composer create-project drupal-composer/drupal-project:8.x-dev some-dir --no-interaction on Ubuntu with PHP 7.0 and in second try with PHP 7.2.

FYI, I was able to get composer to complete by adding this to the composer.json after the first failure and running composer update:

"behat/mink-selenium2-driver": "dev-master as 1.3.x-dev"

Not a long term fix, obviously, but I needed me some Drupal8 now.

same issue for me, doesn't possible to create new project.

"behat/mink-selenium2-driver": "dev-master as 1.3.x-dev" - solution

Just for clarity, This line is to be put in the "required": section of the composer.json file.

Thanks piratawww. This worked great!

The solution @jamie-tillman suggested worked for me too.

[CarlosRinconOmitsis]

The same and the solution @jamie-tillman suggesteds worked like a charm.

The code in my require section of composer.json:

"require": {
    "php": ">=5.6",
    "composer/installers": "^1.2",
    "cweagans/composer-patches": "^1.6.5",
    "drupal-composer/drupal-scaffold": "^2.5",
    "drupal/console": "^1.0.2",
    "drupal/core": "^8.7.0",
    "drush/drush": "^9.0.0",
    "vlucas/phpdotenv": "^2.4",
    "webflo/drupal-finder": "^1.0.0",
    "webmozart/path-util": "^2.3",
    "zaporylie/composer-drupal-optimizations": "^1.0",
    "behat/mink-selenium2-driver": "dev-master as 1.3.x-dev"
},

After edit composer.json: composer update --lock

It seems like every time I install D8 using drupal-composer/drupal-project I have to visit this issue queue to overcome the latest 'cant install' error!

Thanks @jamie-tillman for the temporary fix :)
