急にrailsのサーバーが使えなくなった。

前提・実現したいこと

ruby on railsでアプリ開発を行なっていたところ急にbundle exec rails sができなくなりました。

補足情報（FW/ツールのバージョンなど）

他で似たようなエラーが出てる方もいらっしゃったのですが、その方はrubyのバージョン2.6.0を使ってて起きたみたいで、私が今回使っているのはバージョン2.5.0です。
ruby -v
ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin16]

gemfileにもrubyは2.5.0と書いてあります。
railsは6.0.0です。
