Heroku没有选择正确的web服务器

我想在heroku托管的rails应用程序中使用unicorn。我跟着赫罗库 . 但heroku似乎选择了“瘦”web服务器而不是“独角兽”。下面是我的heroku仪表板的屏幕截图

从这个数据板上，我确信heroku知道我的Procfile，但是当我运行时

heroku ps logs --app vamos-test

我有以下日志

 === run: one-off dyno
 run.1: up for 5m: `bash`

 === web: `bundle exec thin start -p $PORT`
 web.1: created for 30s

从这些日志中，我假设“瘦”是我的应用服务器

我还尝试了一些命令来解决问题：

heroku ps:scale web=1 --app vamos-test 
heroku ps:restart --app vamos-test

但我仍然得到与上面相同的日志

这是我的config/unicorn.rb文件

 #config/unicorn.rb
 worker_processes Integer(ENV["WEB_CONCURRENCY"] || 3)
 timeout 15
 preload_app true

 before_fork do |server, worker|
   Signal.trap 'TERM' do
     puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
   Process.kill 'QUIT', Process.pid
 end

 defined?(ActiveRecord::Base) and
   ActiveRecord::Base.connection.disconnect!
 end

 after_fork do |server, worker|
   Signal.trap 'TERM' do
     puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to send QUIT'
   end

   defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection
 end

#config/unicorn.rb
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb

这里是我的Procfile

 #config/unicorn.rb
 worker_processes Integer(ENV["WEB_CONCURRENCY"] || 3)
 timeout 15
 preload_app true

 before_fork do |server, worker|
   Signal.trap 'TERM' do
     puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
   Process.kill 'QUIT', Process.pid
 end

 defined?(ActiveRecord::Base) and
   ActiveRecord::Base.connection.disconnect!
 end

 after_fork do |server, worker|
   Signal.trap 'TERM' do
     puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to send QUIT'
   end

   defined?(ActiveRecord::Base) and ActiveRecord::Base.establish_connection
 end

#config/unicorn.rb
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb

并且麒麟gem正确地包含在Gemfile中

我错过什么了吗？请帮帮我。从文件中删除

thin

时会发生什么情况？还有你档案里的那一行？另外，我猜你没有真正运行heroku ps日志，对吧？这不是有效的命令？@JonMountjoy我的gem文件中没有thin。Channa，你找到解决方案了吗？@Walksalong还没有。你知道吗？
