Sketchup 2017 and 2018 use Ruby 2.2.x, which is what the OpenStudio suite of tools used for version 2.X.
The - now separated and managed by OpenStudio Coalition - OpenStudio Application and OpenStudio Sketchup Plugin rely on the the OpenStudio SDK (from NREL) at version 3.X, which uses Ruby 2.5.X and that's what Sketchup 2019 uses.
Ruby versions need to align for the plugin to work.
You could use OpenStudio 2.9.1 (which would use E+ v9.2.0 if you do simulate your model) to draw your geometry in Sketchup 2017 Make (free), then open your OSM in the OpenStudio Application 1.1.1 which uses OpenStudio SDK 3.1.0 and EnergyPlus v9.4.0. The problem is if you need to adjust your geometry once you have done that upgrade, since OpenStudio SDK maintains compatbility of OSM files only in one direction (older to newer, which is expected).
