【问题描述】：

使用以下方式部署到 Ubuntu 时出现以下错误：

ruby '2.3.0'
gem 'rails', '~> 4.2', '>= 4.2.5.1'
gem 'rake', '~> 11.3'
gem 'capistrano',  '~> 3.9'

这是我的服务器日志：

【解决方案1】：

如果您尝试从服务器上的应用目录运行gem install nokogiri，您会得到什么？您可能缺少服务器上的一些库。见http://www.nokogiri.org/tutorials/installing_nokogiri.html

【讨论】：

我在本地机器和服务器上再次卸载并安装了 nokogiri。没有解决问题。

【解决方案2】：

我在服务器上重新安装了整个 ubuntu 系统。然后重新安装了 ruby 和 bundler。此后一切正常。
