我正在使用 Capistrano 自动化我的 Rails 部署，并且在启动乘客时在流程结束时遇到错误。我最终出现以下错误：

uninitialized constant PhusionPassenger::Standalone::Command::SERVER_INSTANCE_DIR_STRUCTURE_MAJOR_VERSION

我实际上发现SERVER_INSTANCE_DIR_STRUCTURE_MAJOR_VERSION在[...]/phusion_passenger/constants.rb.

这是完整的堆栈跟踪：

*** [err :: www.example.com] /var/www/production/shared/bundle/ruby/1.9.1/gems/passenger-4.0.4/lib/phusion_passenger/standalone/command.rb:241:in `create_nginx_controller'

我添加了用于从 Capistrano 启动和停止Passenger Standalone 的自定义任务，一切似乎都按预期进行，包括 Passegner 的安装，直到出现这个奇怪的错误。这是我的 Capfile 的相关部分：

set :passenger_cmd,  "#{fetch(:bundle_cmd, "bundle")} exec passenger"
namespace :deploy do
  task :start, :roles => :app, :except => { :no_release => true } do
    run "cd #{current_path} && #{passenger_cmd} start -e #{rails_env} -p #{passenger_port} -d"
  end

  task :stop, :roles => :app, :except => { :no_release => true } do
    run "cd #{current_path} && #{passenger_cmd} stop -p #{passenger_port}"
  end

  task :restart, :roles => :app, :except => { :no_release => true } do
    run <<-CMD
      if [[ -f #{current_path}/tmp/pids/passenger.#{passenger_port}.pid ]];
      then
        cd #{current_path} && #{passenger_cmd} stop -p #{passenger_port};
      fi
    CMD

    run "cd #{current_path} && #{passenger_cmd} start -e #{rails_env} -p #{passenger_port} -d"
  end
end

我的完整设置如下：

  • 导轨 3.2
  • 虚拟机
  • 卡皮斯特拉诺
  • 乘客独立

该错误已在 GitHub 上的提交4ad928d中修复。

您可以尝试使用来自 GitHub 存储库的克隆，或等待包含此修复的版本 4.0.5。

编辑：截至目前，版本 4.0.5 可用。

一种解决方法是降级到Passenger 4.0.3。

gem uninstall passenger
gem install passenger --version="4.0.3"

这似乎是 4.0.4 版本中的一个问题。
