Failed While Installing Nokogiri on Ubuntu

I am trying to install nokogiri on Ubuntu Linux. I am running Ruby-2.1.1. I have installed.

Output:

sudo gem install nokogiri
Building native extensions. This could take a while...
ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

    current directory: /var/lib/gems/2.5.0/gems/nokogiri-1.8.5/ext/nokogiri

mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.5.0/gems/nokogiri-1.8.5 for inspection.
Results logged to /var/lib/gems/2.5.0/extensions/x86_64-linux/2.5.0/nokogiri-1.8.5/gem_make.out

Can anyone explain what I am missing?

Solution

  • Try installing Ruby 2.1.1 with rbenv and set it as default version in ubuntu:

        rbenv install 2.1.1
    rbenv global 2.1.1

    After installing ruby, install the following packages:

    sudo apt-get install libxslt-dev libxml2-dev zlib1g-dev

    And then install nokogiri:

    sudo gem install nokogiri

    This should do the trick...
