composer.json fails to resolve installable set of package - symfony

Question

I can't install stof/doctrine-extensions-bundle with my Composer. I'm using Symfony2.1.9 version and a lot of problems are shown. The first one is:
the requested package stof/doctrine-extensions-bundle 1.1.* could not be found.
This is my composer.json file:
{
"name": "symfony/framework-standard-edition",
"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
"psr-0": { "": "src/" }
},

},
"extra": {
"symfony-app-dir": "app",
"symfony-web-dir": "web",
"branch-alias": {
"dev-master": "2.1-dev"
}
}
}
when i set the package requirement to: "stof/doctrine-extensions-bundle": "1.1.*#dev"
the response was: your requirement could not be resolved to an installable set of package
what could be the problem please??
should i install DoctrineExtensions first????

Answer 1

The critical part in here is the following:
[...]
white-october/pagerfanta-bundle dev-master requires symfony/framework-bundle >=2.2,<3.0 -> satisfiable by symfony/symfony[v2.2.0, v2.2.1], symfony/framework-bundle[v2.2.0, v2.2.1].
[...]
Which can lead to confusion! Let me explain:
Though it says the dependency is satisfiable by updating symfony/symfony to 2.2.0 or 2.2.1 ... this update is NOT NEEDED !! ( even if updating might be a good idea it is not necessary to resolve the issue and could lead to broken code because of BC [backward compatibility] breaks )
Attention:
Many bundles have a legacy branch ... for example a 2.1.x branch to support symfony/symfony 2.1.
Look for these branches on packagist prior to blindly updating your whole project to a new version of the root package!
Tip:
Generally if composer fails to fetch a dependency this is often related to the minimum stability for one of your required packages. minimum stability of all packages normally defaults to stable.
Solution:
smarttech used the wrong branch (dev-master) for white-october/pagerfanta-bundle to use it with symfony 2.1. The correct branch for 2.1 would have been:
"white-october/pagerfanta-bundle": "2.1.*#dev"
... where the #dev stability flag tells composer to use the dev version of doctrine-extensions-bundle for this single package. Please read more about composer's Stability Flags.
Take a quick look at the stability hierarchy:
dev < alpha < beta < rc < stable
Alternative:
Another way to solve the issue would have been setting composer's minimum stability.
Though this is not recommended as it applies to all constraints and as a result you will get unstable versions of all packages.
{
[...]
"require" :
[...]
"minimum-stability" : "dev",
[...]
}

Answer 2

As the 1.1.x branch of the stof/doctrine-extensions-bundle is still only available as dev. So you have to declare it as a dev dependency in composer. Simply:
"stof/doctrine-extensions-bundle": "1.1.*#dev"
Next time take a look at packagist, which versions are available of a desired bundle.
EDIT: And yes, tested this requirement in a fresh symfony install and it works. So if you have errors, edit the complete error message in your question!

Answer 3

As this is a completly different answer. Your problem is not stof/doctrine-extensions-bundle, it's white-october/pagerfanta-bundle. Kids, read the error messages!
How i knew this? Simply copied your composer.json, executed update and got a meaning error message:
white-october/pagerfanta-bundle dev-master requires symfony/framework-bundle >=2.2,<3.0 -> satisfiable by symfony/symfony[v2.2.0, v2.2.1], symfony/framework-bundle[v2.2.0, v2.2.1].
which means, actual versions of pagerfanta-bundle requires symfony 2.2, so you have to upgrade, if you want to use it.
