ruby-on-rails - nokogiri gem - 错误 : Failed to build gem native extension.

Question

我正在尝试使用 capistrano 部署 Rails 应用程序，但是当捆绑安装在服务器 ubuntu 16.04 中时，我遇到了 nokogiri gem 的一些问题

回溯如下:

Tasks: TOP => deploy:updated => bundler:install
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as root@104.236.11.204: bundle exit status: 5
bundle stdout: Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

current directory:
/var/www/denunciabarranquillafinal/shared/bundle/ruby/2.3.0/gems/nokogiri-1.8.1/ext/nokogiri
/usr/local/rvm/rubies/ruby-2.3.0/bin/ruby -r ./siteconf20171113-30499-1nk84ws.rb

Gem files will remain installed in
/var/www/denunciabarranquillafinal/shared/bundle/ruby/2.3.0/gems/nokogiri-1.8.1
for inspection.

An error occurred while installing nokogiri (1.8.1), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.8.1'` succeeds before bundling.

In Gemfile:
  rails was resolved to 4.2.4, which depends on
    actionmailer was resolved to 4.2.4, which depends on
      actionpack was resolved to 4.2.4, which depends on
        actionview was resolved to 4.2.4, which depends on
          rails-dom-testing was resolved to 1.0.8, which depends on
            nokogiri
bundle stderr: Nothing written

我运行了命令

sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev

在我的服务器中，如果我运行“gem install nokogiri”，gem 会正常安装。

我希望有人可以帮助我修复错误。
