Symfony REST: voryx/restgeneratorbundle Installation failed, reverting ./composer.json to its original content

Question

Today, I decided to learn and task myself to create REST API in Symfony2. I have installed composer using this command

curl -sS https://getcomposer.org/installer | php

Now I am installing Voryx REST Generator Bundle using this command

php composer.phar require voryx/restgeneratorbundle dev-master

And I am getting this error

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of package

  Problem 1
    - Installation request for voryx/restgeneratorbundle dev-master -> s
le by voryx/restgeneratorbundle[dev-master].
    - voryx/restgeneratorbundle dev-master requires sensio/generator-bun
 -> satisfiable by sensio/generator-bundle[3.0.x-dev, v3.0.0, v3.0.1, v3
.0.3, v3.0.4, v3.0.5, v3.0.6] but these conflict with your requirements
um-stability
Installation failed, reverting ./composer.json to its original content.

This is the github repository for the bundle

https://github.com/voryx/restgeneratorbundle

========EDITTED======== This is the composer.json file

Please what am doing wrong?

Answer 1

Don't specify the version of the bundle (dev-master) you want to install: simply let the job to Composer simply launch the command:

php composer.phar require voryx/restgeneratorbundle

And will install the version suitable with your current dependency (0.3.0).

For install a sf3 installation version please refer to the doc here: currently exists various way to install it. With composer you can simply run the command:

php composer.phar create-project symfony/framework-standard-edition my_project_name

Hope this help
