ruby-on-rails - 捆绑安装错误安装 nokogiri (1.6.7.2)。Gem 安装但不适用于 rails 应用程序

问题描述

我正在开发一个使用 ruby​​ 2.1.5 的 rails 项目。我下载了 rvm，安装了 ruby​​ 2.1.5，目前正在使用它。我在 Ubuntu 18.04 上。我在运行时收到以下错误bundle install

gem install nokogiri -v '1.6.7.2'此外，当我按照指示尝试时，它安装得很好。在这种情况下，我找不到另一个问题。

我在 El Capitan 上安装 Nokogiri (1.6.7) 时查看了这个问题Error 并尝试了所有解决方案。这可能是我遇到的另一个问题。它可能与rvm有关，但我不确定。

An error occurred while installing nokogiri (1.6.7.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.7.2' --source 'https://rubygems.org/'` 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

          rails-dom-testing was resolved to 1.0.7, which depends on
            nokogiri

但是正如你所看到的，当我运行时， gem install nokogiri -v '1.6.7.2'它看起来没有问题

$ gem install nokogiri -v 1.6.7.2
