Boa tarde, fiz a instalação do jekyll e do ruby seguindo a documentação repassada pelo site. Porém ao executar o “bundle exec jekyll serve” no terminal do VSCode está aparecendo o seguinte erro:

To use retry middleware with Faraday v2.0+, install `faraday-retry` gem

```

O que devo fazer?

are you using faraday-retry? seems like something for an api.

what is Fiber.current? I think the error is saying Fiber doesn’t exist so you can’t get ‘current’.
