我正在开发一个 Rails 4 应用程序，我已经设置我的服务器运行瘦，我正在尝试设置 capistrano 3 进行部署。我正在windows上开发并在linux上部署。目前如果在这条线上失败：

[f98408e4] Command: bundle exec thin restart -O -C config/thin/production.yml

有一个非常奇怪的例外。有趣的是，当我 ssh 到服务器时，导航到当前版本目录并手动执行该命令，它会正确运行。也许你会看到一些我看不到的东西：

Tasks: TOP => deploy:restart

我关于重启的 deploy.rb 任务如下所示：

set :default_env, { rvm_bin_path: '~/.rvm/bin' }
set :rails_env, "production"
namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      within release_path do
        execute "bundle exec thin restart -O -C config/thin/production.yml"
      end
    end
  end
end

正确的语法是：

namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      within release_path do
        execute :bundle, "exec thin restart -O -C config/thin/production.yml"
      end
    end
  end
  before :restart, 'rvm:hook'
end

有一个非常奇怪的例外。有趣的是，当我 ssh 到服务器时，导航到当前版本目录并手动执行该命令，它会正确运行。也许你会看到一些我看不到的东西：

http://www.capistranorb.com/documentation/faq/why-does-something-work-in-my-ssh-session-but-not-in-capistrano/

我会尝试通过一些建议来调试那里列出的内容。
