Currently, I am creating an application using Ruby on rails.
The environment uses macOS and AWS.

Before setting up a project with rails, I downloaded the layout from an external site, edited it with VScode, and created some views.
When I tried to reflect this in rails, there are many files in the layout of the external site, and I am at a loss as to how to reflect them in rails.

After investigating, I found that the plugin creates javascript and stylesheets folders in vendor/assets in rails and divides them by role, so I put it as shown in the picture below, but the layout is reflected. Was not done.

I'm sorry for the beginner's question, but I would appreciate it if you could answer.

    I tried using the asset pipeline.
    (The one who uses javascript_include_tag instead of javascript_pack_tag)

    Asset Pipeline-Rails Guide

    Place the files under assets of the downloaded file in vendor/assets/stream.

    --css /
    --img /
    --img-temp /
    --include /
    --js /
    --vendor /

    Edit the following two files

    app/assets/javascripts/application.js(If not, make it)

    //= require vendors/jquery.min
    // = require vendors/jquery.migrate.min
    //= require vendors/popper.min
    //= require vendors/bootstrap/js/bootstrap.min
    // = require js/global


    / *
     * = require vendors/bootstrap/css/bootstrap
     * = require css/styles
     * /

    js global and css styles got an error if they were named as they are, so
    Actually, I changed the notation of myglobal, mystyles, file name and require.

    Also, on the waySprockets :: Rails :: Helper :: AssetNotPrecompiledI got an error, so I added the following.
    (Rails5 may not give an error)


    Rails.application.config.assets.precompile + =% w (application.js)

    For the file read by application.js/scss, refer to the following "Starter Template"
