我正在尝试运行以下命令来在生产环境中运行服务器：
rackup private_pub.ru -s thin -E production
private_pub.ru 看起来像这样：
# Run with: rackup private_pub.ru -s thin -E production
require "bundler/setup"
require "yaml"
require "faye"
require "private_pub"
Faye::WebSocket.load_adapter('thin')
PrivatePub.load_config(File.expand_path("../config/private_pub.yml", __FILE__), ENV["RAILS_ENV"] || "production")
run PrivatePub.faye_app
我想将配置文件（thin.yml）传递给 Thin，如下所示：
#thin configuration for clazzoo_chat production deployment
user: deploy
group: deploy
所以这是我要执行的命令：
bundle exec rackup $APP_ROOT/private_pub.ru -s thin -C $APP_ROOT/config/thin.yml start -E production
但是 rackup 不支持 -C 因为这个参数是针对瘦的......根据这些文档：https ://github.com/macournoyer/thin/#configuration-files
我还尝试将我的命令更改为：
bundle exec thin -C config/thin.yml -R private_pub.ru start
但后来我得到错误：
Exiting!

Writing PID to current/tmp/pids/thin.0.pid
在我的设置中 - 当机架运行很薄时，如何将此配置（thin.yml）传递给瘦？
