Rails ローカル開発環境構築 *=requireが読み込めない。couldn't find file 'toastr/build/toastr.min' with type 'text/css'

Question

困っていること

現在cloud9上で開発を行っているアプリをVScodeが使いたいのでローカル環境にcloneして開発を進めていこうとしているのですが、エラーメッセージにある通り、application.cssで書いている*= require hogehoge系が読み込めない状態です。
ここら辺のフロントエンドの知識が乏しく、どうすればいいのかわからない状態です。

PJでは別にcustom.css.scssというscssファイルを用意しております。

cloud9上では全く同じコードで同様のエラーは起きないのですが、何が悪いのか不明です。

おそらく、cloud9時と、local時でcssやjs, bootstrap gemなどを読み込む際のpathの違いが発生しているのかもしれませんが、原因がわかりません。

Answer 1

ローカルな必要なパッケージがなかったようです。

% brew install yarn

% yarn install

で直りました。

Chromeだとsslでエラーが出ましたが設定ですかね。
Safariで繋ぐと、localhost:3000を見ることが出来ました
