我似乎无法让捆绑器在部署时与独角兽一起工作。我正在使用 capistrano 进行部署。
在部署时查看独角兽日志，我收到以下错误：

Capistrano 正在清理该应用程序的最后 5 个版本，我看到捆绑程序正在尝试访问一个不存在的（最后删除的）版本。
我找到了我放入 unicorn.rb.erb 的代码，但它没有帮助（我也尝试对其进行硬编码）： http ://davidvollbracht.com/blog/headachenewunicorn-capistrano-bundler-usr2
before_exec do |server|
ENV['BUNDLE_GEMFILE'] = "<%= current_path %>/Gemfile"
end
部署我的代码后，我启动和停止了 NGINX，启动和停止了 unicorn，但我遇到了同样的问题。
我关于堆栈溢出的原始帖子在这里，但我认为它与资产管道有关：资产管道不在 Rails 生产环境中工作
想法？
这是我的 unicorn.rb.erb 文件：
working_directory "<%= current_path %>"
pid "<%= unicorn_pid %>"
stderr_path "<%= unicorn_log %>"
stdout_path "<%= unicorn_log %>"
listen "/tmp/unicorn.<%= application %>.sock"
worker_processes <%= unicorn_workers %>
timeout 30
preload_app true
before_exec do |server|
ENV['BUNDLE_GEMFILE'] = "<%= current_path %>/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
end
after_fork do |server, worker|
# Start up the database connection again in the worker
if defined?(ActiveRecord::Base)
ActiveRecord::Base.establish_connection
end
end
这是我的 unicorn_init.sh 文件：
