Bit of a newb so I apologise.

I want to create a local dev environment of a live website.

I can clone the codebase but am not able to copy the database as yet I appreciate that may be the cause of my issue.

Failing at the first hurdle of building the solution. Below is my error caused by Umbraco.ModelsBuilder.

Is this likely to be because i don't yet have a local copy of my DB? or will I need to solve this in addition to copying the db?
