ExecJS::ProgramError after adding bootstrap gem

After adding the bootstrap gem to my brand new Rails app and importing it in application.scss, my pages fail with

ExecJS::ProgramError in Home#index
Showing C:/Source/Repos/graph-tutorials/ruby-test/app/views/layouts/application.html.erb where line #8 raised:

identifier '(function(opts, pluginOpts) {return eval(process' undefined
Rails.root: C:/Source/Repos/graph-tutorials/ruby-test

• Ruby 2.5.1
• Rails 5.2.0
• Windows 10

Steps to reproduce:

1. Run rails new ruby-test

2. CD to ruby-test, edit Gemfile

3. Change sqlite3 line to load from GitHub (for Ruby 2.5 on Windows compatibility):

   gem 'sqlite3', git: 'https://github.com/sparklemotion/sqlite3-ruby'
   

4. Run bundle install

5. Run rails generate controller Home index

6. Run rails server

7. Browse to http://localhost:3000/home/index and verify the page renders

8. Add bootstrap to Gemfile, bundle install

9. Rename application.css to application.scss, replace contents of file with:

   // Custom bootstrap variables must be set or imported *before* bootstrap.
   @import "bootstrap";
   

10. Restart server

11. Browse to http://localhost:3000/home/index, see error.

Reproduce the failure using the listed Windows, Ruby, and Rails versions, then inspect Gemfile, app/assets/stylesheets/application.scss, and the layout entry at app/views/layouts/application.html.erb. Start with the bootstrap import and asset compilation path; done means the Home#index page renders after the import without an ExecJS::ProgramError.
