Webpackerがアプリケーションを見つけられない
「Railsの概要」に従って、新しいRailsアプリケーションを作成しています。アプリケーションはステップ4.1で正常に起動します。しかし、最初のコントローラーを作成すると、webpackエラーが発生します。
私はwebpackの初心者ですが、すべてのドキュメントが赤ですが、何が問題なのか、何が欠けているのかわかりません...

Webpacker successfully installed �????????????
Webpacker::Manifest::MissingEntryError in Welcome#index
Showing C:/Users/[...]/site_test/app/views/layouts/application.html.erb where line #9 raised:
Webpacker can't find application in C:/Users/[...]/site_test/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.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:
{

ご協力いただきありがとうございます。残念ながら何も機能しません。
Railsの資産：clobberは、node_modulesフォルダーを削除した直後に「整合性ファイルが見つかりませんでした」というエラーを返します。 （yarn install --check-filesの後に機能します）。
およびRails assets：precompile return "C：/Ruby26-x64/lib/Ruby/gems/2.6.0/gems/webpacker-4.0.7/lib/webpacker/webpack_runner.rb：23 ： `exec '内：そのようなファイルまたはディレクトリはありません-C：\ Users [...]\site_test\node_modules.bin/webpack（Errno :: ENOENT）"
しかし、私は何が間違っているのかを発見しました：私のコンピューターの場所！おそらく名前の問題...
