Railsのwebpackerのエラー

Question

railsでwebpackerを導入したところ、サーバーを起動することはできましたが、コントローラーとviewファイルを追加し、localhostでアクセスしたところ、we are sorry, but something went wrongが表示されます。```Ruby
コード

C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/webpacker-5.2.1/lib/webpacker/webpack_runner.rb:23:in `exec': No such file or directory - C:\Users\username\sample_app\node_modules.bin/webpack (Errno::ENOENT)
        from C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/webpacker-5.2.1/lib/webpacker/webpack_runner.rb:23:in `block in run'
        from C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/webpacker-5.2.1/lib/webpacker/webpack_runner.rb:22:in `chdir'
        from C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/webpacker-5.2.1/lib/webpacker/webpack_runner.rb:22:in `run'
        from C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/webpacker-5.2.1/lib/webpacker/runner.rb:6:in `run'
        from ./bin/webpack:17:in `block in <main>'
        from ./bin/webpack:16:in `chdir'
        from ./bin/webpack:16:in `<main>'
このようなエラーコードが出ます。
