[FIXED] InvalidArgumentException when attempting to install facebook/php-sdk-v4 via composer

Issue

I'm attempting to install the latest Facebook SDK via composer however I receive this error:

$ composer require facebook/php-sdk-v4


  [InvalidArgumentException]                                                                                                                           
  Could not find package facebook/php-sdk-v4 at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability  

After reading the upgrade guide I thought that perhaps my php version is not compatible so I checked the version:

$ php -v

How can I resolve this and get the Facebook SDK installed? Thanks

Solution

It took some more digging but I finally figured out the problem with this installation. I'm using Symfony 2.8 and it seems that the default Symfony projects preconfigure composer with a default php version even though you may have a higher version installed. The version string is in the config section of composer.json

"config":{
  "bin-dir":"bin",
  "platform":{
    "php":"5.3.9"
  }
}

Once I changed the value to 5.4.0 I was able to install the Facebook SDK.
