在 Windows 10 ruby​​ on Rails 中连接到 Redis 服务器

Question

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

好吧，我遇到了同样的问题，并且它对我来说适用于以下cable.yml 配置：

development:
  adapter: async

疯狂的是，它实际上正在连接到我本地的 redis 服务器！我猜想它根本不应该在该配置中使用 redis，但它正在使用它并且工作得很好。

相反，如果我设置了我认为正确的配置，它就会失败：

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

这是错误：

C:/RailsInstaller/Ruby2.3.​​0/lib/ruby/gems/2.3.0/gems/redis-3.3.3/lib/redis/client.rb:345:in `rescue in acquire_connection': 连接到本地主机上的 Redis 时出错:6379 (Redis::超时错误) (Redis::无法连接错误)

所以，我不确定为什么，如果有人可以解释它，但为我解决它，那就太好了adapter: async（Rails 5.0.7，Windows 10，redis gem 3.3.3）。
