webpackerを使用して新しいrails 5.1アプリケーションでページを読み込もうとすると、このエラーが発生します。 webpackerにもCSSを扱いたいと思います。stylesheet_pack_tag webpacker gemを含むrails 5.1のapp/javascript/src/application.cssが見つかりません

ActionView::Template::Error (Webpacker can't find application.css in /Users/myusername/Documents/testing-ground/myapp/public/packs/manifest.json. Possible causes:
1. You want to set wepbacker.yml value of compile to true for your environment
unless you are using the `webpack -w` or the webpack-dev-server.
2. Webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your Webpack configuration is not creating a manifest.
Your manifest contains:
{
"application.js": "/packs/application-1ba6db9cf5c0fb48c785.js",
"hello_react.js": "/packs/hello_react-812cbb4d606734bec7a9.js"

私はrails serverと一緒./bin/webpack-dev-serverを実行しています。 bundle bundle exec rails webpacker:install:react
rails new myapp --webpack 私は、単一のCSSファイルapp/javascript/src/application.cssを持っている：私は使ってアプリを作成しました。 （何かが間違っていると感じるように書く）
ただ一つのルートが定義されているroot to: 'home#welcome'。ここで
はここapp/views/layouts/application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Myapp</title>
<%= csrf_meta_tags %>
<%= javascript_pack_tag 'application' %>
<%= stylesheet_pack_tag 'application' %>

である私はアップフロントあまりにも多くの詳細を追加したくない私のconfig/webpacker.yml（私は開発中falseにコンパイル設定も試してみました。
