ActionView::MissingTemplate in Users::Registrations#newのエラー

ActionView::MissingTemplate in Users::Registrations#newのエラーが起こり解決の仕方がわかりません。
railsのエラー作成時、新規登録画面のページに登録しようとしたところこのようなエラーが出ました。エラーの意味がわからず解決の仕方が見いだせない状態です。
railsで勉強し始めたばかりなので、知識不足の部分も多いですが、回答いただけると助かります。

試したこと
・ログインはできるのですが、ログインした後ログアウトし、新規登録した際エラーが出ます。
・error文の理解はできたのですが、どこをどうすれば良いかわかりません

参考サイト
・ログイン画面を作る際はこのサイトを参考にしました。
