Have you met the prerequisites described here: 
https://docs.skuid.com/v11.0.2/en/tutorials/salesforce/skuid-for-sales-lightning.html

Prerequisites

Before you begin, there are three major preparatory steps that must be taken for any org where this package may be installed:

  1. A Lightning-enabled Salesforce org
  2. My Domain must be enabled within the org.
  3. Skuid v10.0.0 or higher must be installed in the org
Finally, Skuid recommends testing this package within a fresh developer org. Doing so will allow you to become familiar with the package, note the amount of settings it requires, and better understand how it will fit within the unique customizations of your own production orgs.
