错误提示

An error occurred while installing nokogiri (1.6.8), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.8'` succeeds before bundling.

请有经验的同志帮忙看看！谢谢。

先运行 gem install nokogiri -v '1.6.8' 就可以看到具体的错误，然后 Google 上一搜，应该还好解决的。

#1 楼 @qinfanpeng 我按照你说的运行了gem install nokogiri -v '1.6.8' 报错是这样的

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.4.

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

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

If you are using Bundler, tell it to use the option:

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

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

正好前几天配环境遇到: 安装 libxml2 and libxslt

brew unlink gcc-4.2      # you might not need this step
gem uninstall nokogiri
xcode-select --install
gem install nokogiri

https://ruby-china.org/wiki/install_ruby_guide 一步步来，你要相信这里很多人都经历过你遇到的问题，都是网上找到了答案才到现在这一步的。

看自己的报错

ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

拿去搜索，然后找答案，你也可以尝试去 github 搜 nokogiri 的 wiki，文档里有更详细的安装指南

可以先尝试先把 gcc 和 js 相关的东西装上，搜 ruby gcc js
