Question

我正处于应用程序的部署阶段并发现了一些错误......我正在使用Capistrano和Mongrel，而deploy.rb文件就是这样的

set :application, "ngs_app"
set :repository,  "file:///Users/Admin/svnrepo/#{application}"
set :deploy_to,   "/Library/WebServer/#{application}"
set :deploy_via,  :export
set :scm_username, "Admin"
set :scm_password, "##########"
set :scm, :subversion
ssh_options[:forward_agent] = true

# Or: `accurev`, `bzr`, `cvs`, `darcs`, `git`, `mercurial`, `perforce`, `subversion` or `none`

role :web, "130.209.53.216"                          # Your HTTP server, Apache/etc
role :app, "130.209.53.216"                          # This may be the same as your `Web` server
role :db,  "130.209.53.216", :primary => true        # This is where Rails migrations will run
# role :db,  "your slave db-server here"
# Adding Mongrel_specific variables
set :mongrel_cmd, "/usr/bin/mongrel_rails_persist"
set :mongrel_ports, 3000..3003
set :user, "Admin"
set :group, "administrator"

# Adding Capistrano tasks 
namespace :deploy do
desc "Start Mongrel processes and add them to launchd. "
task :start, :roles => :app do 
  mongrel_ports.each do |port|
    sudo "#{mongrel_cmd} start -p #{port} -e production --user #{user} --group #{group} -c #{current_path}"
  end
end
desc "Stop mongrels processess and remove them from launchd. "
task :stop, :roles => :app do 
  mongrel_ports.each do |port|
    sudo "#{mongrel_cmd} stop -p #{port}"
  end
end
desc "Restart Mongrel processes"
task :restart, :roles => :app do 
  stop 
  start
end
end

The error message I get are the following

有人可以帮我解决耙子流产的问题吗？提前谢谢

Answer 1

有些可能性如下：

有人修改了现有的db_migration_XXX.rb脚本。从生产数据库的角度来看，此脚本已经运行
数据库迁移脚本中有多个预期的操作，如果脚本在运行时第一次中止并且您尝试重新运行脚本，则通常会发生此类问题。

开发模式与生产模式不匹配。耙子流产了
