Answer 1

I came across the same problem running composer.phar install with Symfony3 on Mac OS (Mavericks) with MAMP: script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap handling the post-update-cmd event terminated with an exception.

Solved by updating the PHP version from 5.4 to 5.6. As Symfony runs inside MAMP, I forgot that my system default PHP version is not supported by Symfony3. After the PHP upgrade, the composer run with success.
