vendor/assets配下のstylesheetsとjavascriptsが認識されない

エラー内容

vendor/asssets/stylesheets配下にcssファイル、vendor/assets/javascripts配下にjsファイルを追加し、

それそれ以下のように読み込ませる指定をしたのですが、読み込んでくれないエラーに遭遇しました。

app/assets/stylesheets/application.css

*= require_tree .
*= require jquery.tagit
*= require tagit.ui-zendesk
*= require_self
*/

app/assets/javascripts/application.js

//= require jquery
//= require rails-ujs
//= require jquery-ui
//= require tag-it
//= require activestorage
//= require turbolinks
//= require_tree .

調査

ググってみると、パスが通っていない可能性が考えられるとのことで、以下のコマンドで確かめてみました。

すると、やはり、vendor/assets/stylesheetsとvendor/assets/javascriptsのパスは通っておりませんでした！！

解決方法

パスを通すためには、config/initializers/assets.rbに以下のように指定すれば良いとのことでした。

Rails.application.config.assets.paths << Rails.root.join("vendor", "assets", "javascripts")
Rails.application.config.assets.paths << Rails.root.join("vendor", "assets", "stylesheets")

この状態でもう一度パスが通ったか確認してみると、きちんと通っておりました！！
