mini_racer および libv8-node をインストールするための gem ネイティブ拡張機能 (Windows 10) のビルドに失敗しました

概要

jekyll を使用して Web サイトを生成するために、bundle exec jekyllserve を使用しようとしましたが、次の結果が返されました。

それでバンドルインストールをしました

そしてこのエラーが発生しました:

An error occurred while installing libv8-node (18.16.0.0), and Bundler cannot
continue.

In Gemfile:
  mini_racer was resolved to 0.8.0, which depends on
    libv8-node

gem install libv8 も試してみましたが、次のように返されました。

gem update も試してみましたが、gem が更新されたことがわかりました。また、winget で Ruby-dev をインストールしたところ、次の結果が返されました。

解決策

「therubyracer」を使用して「mini_racer」を置き換え、Windows システム上で「bundle install」と「bundle exec jekyll s」を正常に完了しました。このデバイスを受け取っていただければ幸いです。
