************************************************************************
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.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /Users/ChamperWu/.rvm/gems/ruby-2.3.1@rails500/extensions/x86_64-darwin-16/2.3.0/nokogiri-1.6.8.1/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /Users/ChamperWu/.rvm/gems/ruby-2.3.1@rails500/gems/nokogiri-1.6.8.1
进行检查。结果记录到/Users/ChamperWu/.rvm/gems/ruby-2.3.1@rails500/extensions/x86_64-darwin-16/2.3.0/nokogiri-1.6.8.1/gem_make.out

我尝试再次卸载并安装它，但我得到了相同的信息

我该如何解决？

Answer 1

这可能会有所帮助：

brew uninstall xz

gem install nokogiri -v 1.6.8或gem install rails（您正在运行的命令）

无法使用rvm install rails 5 gem
