wrong constant name (NameError) が解決できない。

Question

$docker-compose run --rm app rails new . --force --database=mysql --skip-
をするとname errorになります。どうすれば解決できるでしょうか。

初学者なもので的外れな質問になってしまうかもしれませんが申し訳ありません。ご教授いただけたら幸いです。

エラー文はこの通りです。

$ docker-compose run --rm app rails new . --force --database=mysql --skip-bundle
