Recently switched from a Mac to a PC and hit a wall with `bundle install`. 

I get an error but I'm have trouble figuring out what it means and how to fix it. I searched through the GitHub issues and other StackOverflow threads, but none of the fixes suggested help me because they're focused on Linux mostly. 

```
Bundler found conflicting requirements for the Ruby  version:
  In Gemfile:
    Ruby  (~> 2.6.5.0)

    pg was resolved to 0.21.0, which depends on
      Ruby  (< 2.5) x64-mingw32

Ruby  (< 2.5), which is required by gem 'nokogiri (>= 1.4.1)', is not available
in the local ruby installation
