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:

Can anyone explain what I am missing?
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...

I use Linux Mint and I want to install sass. I have installed ruby by "sudo apt install ruby" , version 2.3 and then , when I wan to install sass by "sudo gem install sass --no-user-install" , I have the following error:

Install this package:
sudo apt install ruby-dev
The ruby-dev package contains the missing headers. You can see that the installer is looking for the headers:
/usr/lib/ruby/include/ruby.h
Installing this package will install those headers. This is a common issue that comes up for new Ruby users when installing gems with native extensions. You may find that you have to install several packages to get the installation to complete. If you see similar errors when installing this gem or other gems, try searching for "gemname native extension prerequisites", like "sass gem native extension prerequisites", to learn which packages should be installed before installing the gem.
Try this:
sudo apt install ruby-full rubygems autogen autoconf libtool make
sudo gem install sass
I had the same issue on Ubuntu 18.04, ruby-dev itself didn't help, installing g++ and make, as stated here solved my issue.

I had this same problem. I solved it by
sudo apt-get install sqlite3 libsqlite3-dev
Then the following command worked.
sudo gem install sqlite3-ruby
