我在 Windows 10 上的 Rails 应用程序中连接到 Redis 时遇到问题，我将 Redis 添加到了 gem 文件中并设置了 Cable.yml 文件。当我启动 Rails 服务器时遇到的错误是rescue in establish_connection': Timed out connecting to Redis on localhost:6379如何解决这个问题。

电缆.yml

development:
  adapter: redis
  url: redis://localhost:6379/1

test:
  adapter: async

production:
  adapter: redis
  url: redis://localhost:6379/1

命令行

我正在尝试安装 spree gem，但在安装 gem 时遇到了一些麻烦。目前我在尝试安装 rabl(0.13.1) gem 时遇到错误。我得到一个许可被拒绝。想知道如何修复此错误，以便我可以回去完成安装狂欢。
