运行Bundle Install时Nokogiri v 1.8.1问题

Question

当运行Bundle Install或Gem Install Nokogiri时,我遇到了阻止我的应用程序运行的相同问题.我怀疑这个问题是本地的,并且是将所有内容都移到了Rails 5,但我不确定.这是错误消息:

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_admin was resolved to 1.2.0, which depends on
    rails was resolved to 5.1.3, which depends on
      actioncable was resolved to 5.1.3, which depends on
        actionpack was resolved to 5.1.3, which depends on
          actionview was resolved to 5.1.3, which depends on
            rails-dom-testing was resolved to 2.0.3, which depends on
              nokogiri

(这来自运行Bundle Install)我尝试运行Bundle Update并使用Gi​​thub推荐的各种Homebrew命令,但我没有取得任何成功.

gem install nokogiri -v'1.8.1'

1 error generated.
make[2]: *** [xmlIO.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
========================================================================
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Answer 1

(对于UBUNTU)首先尝试这样做

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

然后尝试安装.

Answer 2

Nokogiri无法正常构建,因为你没有像libxml2这样的开发库.查看日志文件以查看发生了什么或尝试直接安装libxml2brew install libxml2

请参阅Nokogiry在http://www.nokogiri.org/tutorials/installing_nokogiri.html提供的引导指南

我只是发布找到的解决方案（我在MacOS上也遇到了同样的问题）。这样，将使用系统库来安装gem，这将解决您遇到的问题。

1. 如果使用gem：

gem install nokogiri -- --use-system-libraries
 [--with-xml2-config=/path/to/xml2-config]
 [--with-xslt-config=/path/to/xslt-config]

2. 如果使用捆绑包：

bundle config build.nokogiri --use-system-libraries
bundle install
