Question

我有一个使用独角兽aws上的nginx的Rails应用。我刚刚将ruby版本从2.0更新到了2.2.1。

ruby -v返回

红宝石2.2.1p85（2015-02-26修订版49769）[x86_64-linux]

我试图重新启动独角兽服务

sudo service unicorn_game-mercenaries_production stop
sudo service unicorn_game-mercenaries_production start

结果是

/home/gamemercs/.rvm/gems/ruby-2.2.1@game-mercenaries/gems/bundler-1.10.6/lib/bundler/definition.rb:412:in validate_ruby!': Your Ruby version is 2.0.0, but your Gemfile specified 2.2.1 (Bundler::RubyVersionMismatch) from /home/gamemercs/.rvm/gems/ruby-2.2.1@game-mercenaries/gems/bundler-1.10.6/lib/bundler.rb:123:in设置”来自 /home/gamemercs/.rvm/gems/ruby-2.2.1@game-mercenaries/gems/bundler-1.10.6/lib/bundler/setup.rb:18:in <top (required)>' from /usr/share/ruby/vendor_ruby/2.0/rubygems/core_ext/kernel_require.rb:55:in require'from /usr/share/ruby/vendor_ruby/2.0/rubygems/core_ext/kernel_require.rb:55:in `require'

这是我的unicorn.rb：

stdout_path "/home/gamemercs/rails_apps/game-mercenaries/shared/log/unicorn.stdout.log"

listen "/tmp/unicorn.game-mercenaries_production.sock"


worker_processes 2
timeout 30

preload_app true

before_exec do |server|
  ENV["BUNDLE_GEMFILE"] = "/home/gamemercs/rails_apps/game-mercenaries/current/Gemfile"
end

before_fork do |server, worker|
  # Disconnect since the database connection will not carry over
  if defined? ActiveRecord::Base
    ActiveRecord::Base.connection.disconnect!
  end

  # Quit the old unicorn process
  old_pid = "#{server.config[:pid]}.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end

  if defined?(Resque)
    Resque.redis.quit
  end
  p 'stop'

  sleep 1
end

after_fork do |server, worker|
  # Start up the database connection again in the worker
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
  end

  p 'start'
  if defined?(Resque)
    Resque.redis = 'localhost:6379'
  end
end

我将不胜感激。如何让独角兽使用默认的ruby（v2.2.1）？

Answer 1

能否请您在/etc/init.d/unicorn中编辑GEM_HOME和GEM_PATH以反映您的新红宝石版本路径/编号？

独角兽不使用默认的红宝石版本
