Can't generate bootstrap file in Symfony 2.1.1

Question

I've got an application written for Symfony 2.0 and I've started migrating it into Symfony 2.1. I've successfully installed all the dependencies with composer but a script fails...

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap handling the post-update-cmd event terminated with an exception



  [RuntimeException]                                     
  An error occurred when generating the bootstrap file.  

Any clue? I'm completely lost and I've googled it but I've only found a post in a forum with people having the same problem as me...

Answer 1

The problem is that the manual is not clear. It tells you to execute composer.phar install before telling that symfony-standard files need to be replaced.

So now you have to replace

• AppKernel.php,
• AppCache.php and
• autoload.php (and remove odd files)

and update your config.yml file with the given tips.
