ruby-on-rails - Capistrano 不安装

Question

每当我尝试运行 cap production deploy它在以下命令失败

[ebbf9fde] Command: cd /var/www/apps/my_app/releases/20150803171251 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/my_app/shared/bundle --without development test --deployment --quiet
DEBUG [ebbf9fde]    /usr/local/rvm/scripts/set: line 19: exec: bundle: not found

我添加了一个用户“部署”来执行此部署，输出 rvm list是

$ rvm list

rvm rubies

=* ruby-2.2.2 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

进一步运行 gem list 输出是

$ gem list

我的 Capfile内容是

require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

最后我的 deploy.rb 包含以下数据。

    end
  end

  after :publishing, :restart
  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:

      #   execute :rake, 'cache:clear'
      # end
    end
  end
end


namespace :deploy_prepare do
  desc 'Configure virtual host'
  task :create_vhost do
    on roles(:web), in: :sequence, wait: 5 do
    vhost_redirect_config = <<-EOF

end
end

after "deploy:finished", "deploy_prepare:create_vhost"
after "deploy_prepare:create_vhost", "deploy:httpd_graceful"
after "deploy:httpd_graceful", "deploy:restart"

我收到以下错误

Answer 1

试试看 gem install bundler在服务器上一次将 bundler 安装到 rvm gemset 中，因为它不在您的列表中 gem list .

一般来说尽量确保bundle当您通过 ssh 登录服务器时，命令会运行。 Capistrano 不会施展魔法，它只是通过 ssh 登录并发出命令。您始终可以看到 capistrano 发出哪些命令，例如在您的示例中 cd /var/www/apps/oxygen/releases/20150803172155 && /usr/local/rvm/bin/rvm 2.2.2 do bundle install --path /var/www/apps/oxygen/shared/bundle --without development test --deployment --quiet并在出现故障时自己尝试。
