Redis 正在运行，我还没有创建任何 worker。

我可以启动 Rails 服务器。

这是一个错误吗？

Answer 1

您可能会有一个不匹配的文件名，以错误的方式映射类名(可能是拼写错误)。

寻找类似“嵌套 Controller ”的东西，它包含一个具有不同名称的类声明......类似于以下内容:

app/controllers/trash?/your_controller.rb

class Trash::YourController < ApplicationController
  def index
    ...
  end
end

看到 trash? (dirname) 和相关类名 Trash 之间的不匹配/拼写错误。
