rails s LoadError: cannot load such file -- refile/simple_form

Question

• I am having an issue with when I run rails s. I am working on a legacy application and attempting to upgrade to the latest versions of rails and ruby. Current application is using ruby 2.5.0 and rails 5.2.8. The issue is centered around the following:

/Users/user/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/bootsnap-1.11.1/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:15:in require': cannot load such file -- refile/simple_form (LoadError)

• When I run bundle install it is successful rendering the following results:

Bundle complete! 43 Gemfile dependencies, 150 gems now installed. Use bundle info [gemname] to see where a bundled gem is installed. 1 installed gem you directly depend on is looking for funding. Run bundle fund for details

• When I run bundle fund I get the following:

cancancan (3.3.0) Funding: https://github.com/sponsors/coorasse

• I then at cancancan (3.3.0) to my gemfile and run bundle install again which results successfully. I try to run rails s and I continue to get the same error. Any help would be greatly appreciated.
  I even tried to set the gem refile to gem 'refile', require: ['refile/rails', 'refile/simple_form']. This does not make a difference.

Current Error after running rails s

end

Answer 1

The gem for the missing resource is commented out in your Gemfile:

# gem 'refile', require:  'refile/simple_form'

Also, make sure that the version of refile being installed is at least 0.6.0 (i.e., the version where simple_form support was introduced.) Sometimes conflicts cause bundler to go back to refile 0.3.0.
