SSHKit::Command::Failed：捆绑标准输出：没有为 capistrano 编写

Question

当我在做cap production deploy 时，我收到以下错误：

cap aborted!
SSHKit::Command::Failed: bundle stdout: Nothing written
bundle stderr: Nothing written

宝石文件：

gem 'capistrano'
gem 'capistrano-rails', '~> 1.1'
gem 'rvm1-capistrano3', require: false
gem 'capistrano-bundler'

Capfile：

# Load DSL and Setup Up Stages
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rails'
require 'capistrano/bundler'
require 'rvm1/capistrano3'

# Includes default deployment tasks

# Includes tasks from other gems included in your Gemfile

# require 'capistrano/rbenv'
# require 'capistrano/chruby'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

你有多少内存？

我自己刚刚解决了这个问题，确实是内存问题。

你可以试试：

1. 重启服务器，再次尝试部署。
2. 增加服务器上的 SWAP。
