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.

Your mac lack of Command Line Tools, go to https://developer.apple.com/download/more/ download the “command line tools” and install, and you will fix it.

Thanks @QinYaffeei -- your suggestion solved the issue for me (macOS 10.11 el capitan)

I faced the same issue while installing nokogiri, Installing with system libraries ( gem install nokogiri -- --use-system-libraries ) solved it

nomad-cli / shenzhen

Install Error "use of undeclared identifier 'LZMA_OK'" #334
