所以自从我开始使用websocket-rails宝石以来，我一直有这个问题。 显然它无法自动加载我的"广播控制器"，并且阻止我在命令行上运行 rails 命令。
我曾经通过注释掉事件文件并加载东西来解决这个问题。 老实说，这是一个废话，有时它有效有时不起作用，但最近我没有让它工作，我一直在尝试调试它一段时间，但老实说我卡住了。
这只发生在开发中。
有人有什么想法吗？

# You can use this file to map incoming events to controller actions.
# One event can be mapped to any number of controller actions. The

# subscribe :client_connected, 'groups#new_user'
#
# Uncomment and edit the next line to handle the client connected event:
# subscribe :client_connected, :to => Controller, :with_method => :method_name
#
# Here is an example of mapping namespaced events:
# namespace :product do
# subscribe :new, :to => ProductController, :with_method => :new_product
# end
# namespace :chatroom do
# subscribe :create_room, "groups#create_room"
# subscribe :update_members, 'groups#update'
# end
# namespace :members do
subscribe :register_member, "broadcasts#register_member_to_group"
subscribe :unregister, "broadcasts#delete_member_from_group"
subscribe :cover_member, "broadcasts#cover_member_for_group"
subscribe :activate_member, "broadcasts#activate_member"
subscribe :deactivate_member, "broadcasts#deactivate_member"
subscribe :send_chat_message, "broadcasts#send_chat_message"

subscribe :group_updated, "broadcasts#group_updated"
subscribe :check_in_member, "broadcasts#check_in_member"
subscribe :check_out_member, "broadcasts#check_out_member"

# The above will handle an event triggered on the client like `product.new`.
