Hey @stevejohnson,
We recommend installing through Bitnami, it's super easy. 
You can use an array of hosts: https://bitnami.com/stack/dreamfactory/cloud
DreamFactory supports your local hosts: http://wiki.dreamfactory.com/DreamFactory/Installation
As for your error: This error is usually caused by improper migration, or improper file permissions. If you turn on DEBUG mode in your .env file you can get more detailed information in your DreamFactory log.
Since this issue has not been determined to be a bug, but rather falls into the category of installation troubleshooting.
Thanks,
@AlexBowen
