Running DreamFactory 2.0 on BlueMix

问题

I am trying to get DreamFactory 2.0 running on BlueMix. I have followed the instructions found at https://developer.ibm.com/bluemix/2014/06/17/getting-started-laravel-bluemix/ on running Laravel applications on BlueMix. I have everything under htdocs except for .bp-config, .cfignore, manifest.yml and composer.json. I have modified the path to artisan for all the scripts in composer.json and then did

cf push df2

In the log messages, I see the php buildpack getting installed, all the modules and then

/tmp/staged/app/php/bin/php /tmp/staged/app/php/bin/composer.phar install --no-progress --no-interaction --no-dev

The dependencies get installed just fine, then I see

}

The dreamfactory:pull-migrations command in the post-install-cmd and post-update-cmd gather all the migrations from the vendor directory (I know, I know. Not my design) and puts them in the htdocs/database/migrations directory. The dreamfactory:setup command will create the .env file, runs key:generate, migrate and db:seed

Based on the error message, it sounds like the dreamfactory:pull-migrations isn't getting run or is erroring out, but since the app doesn't start, I have no way of looking at the file structure.

Does anybody have any ideas on why it isn't working? We're using Laravel 5.1.

Thanks!
