Ruby on Rails 環境構築質問

前提・実現したいこと

プログラミング初心者の者です。
ruby on railsの環境構築の際、いつも同じところでエラーが出ます。

gemをインストールする際に下記のコードを実行
bundle install --path vendor/bundle

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
さらに
An error occurred while installing puma (4.3.5), and Bundler cannot
continue.
Make sure that gem install puma -v '4.3.5' --source 'https://rubygems.org/'
succeeds before bundling.

と表示されます。
ググって色々試したのですが、、解決できません。

アドバイスお願いします。よろしくお願いします。

いや、これはcheckでつかったprogramのソースですから違いますね。もっと後かと
