An error occurred while installing puma (2.11.0), and Bundler cannot continue.
Make sure that `gem install puma -v '2.11.0'` succeeds before bundling.

環境構築をする際に、pumaのインストールで躓いております。

調べていると似たような問題を抱えている人がいたため、それを元に実行していたのですが、
結果的にはダメでした。

ssl周りのエラーなのかと思い以下も実行しました。

$ brew link openssl --force
$ brew upgrade openssl

どなたか原因がわかる方がいらっしゃいましたら、ご助言いただけないでしょうか？

宜しくお願いします。
