【rails2.5.3】rails g~コマンドが通りません。

vagrant環境にて、表題の通り、rails gコマンドが通りません。
また、作成中のアプリ名はfinal-cdeeenという名前です。

エラーメッセージは以下の通りです。

使っている、バージョンは以下の通りです。

vagrant@ubuntu-bionic:/vagrant/final-cdeeen$ rails -v
Rails 5.2.4

vagrant@ubuntu-bionic:/vagrant/final-cdeeen$ ruby -v
ruby 2.5.7p206 (2019-10-01 revision 67816) [x86_64-linux]

vagrant@ubuntu-bionic:/vagrant/final-cdeeen$ bundler -v
Bundler version 2.0.2

試したこと

rubyのバージョンをrbenvで2.6から、2.5.3に変更しました。
ffiというgemが入っていないのではと思い、

$ gem install ffi -v 1.0.9
をし、ffiをインストールしましたが、ダメでした。

補足

初心者なので分からないことが多いですがよろしくお願いします。

これで解決するかどうかよくわかりませんが、ためしに $ rails g model sample ではなくて $ bundle exec rails g model sample にしてみたらどうでしょうか？また、そもそも rails new や rails s が成功していたかどうかなども知りたいです。
