Capistrano在nokogiri上部署滑轨失败

Question

使用部署到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：

Answer 1

如果您尝试从服务器上的应用程序目录运行gem install nokogiri ，会得到什么？ 您可能缺少服务器上的某些库。 请参阅http://www.nokogiri.org/tutorials/installing_nokogiri.html

Answer 2

我在服务器上重新安装了整个ubuntu系统。 然后重新安装红宝石和捆绑器。 此后一切正常。
