Trying to get the gem mysql2 to install and I just cannot get it to work. Before trying to install I installed the following
sudo apt-get install mysql-client libmysqlclient-dev
Then I go to install mysql2 and get
sudo gem install mysql2
Here is the error I am getting. Thanks

you need ruby-dev
sudo aptitude install ruby1.9.1-dev
should fix it.

I am installing riemann monitoring tool on my PC. I run the following command from terminal:
Command:
sudo gem install riemann-tools
I get the following error:
ERROR: Error installing riemann-tools:
ERROR: Failed to build gem native extension.

A similar error comes when installing riemann-dash but riemann-client get installed successfully.
I am using Ububtu 12.10.
I read online about such errors and it had something with ruby version, but I am not able to figure out the reason for this.
Any help is appreciated.
this solved it for me:
For Debian/Ubuntu
apt-get install ruby-dev zlib1g-dev
For RedHat/CentOS/Fedora:
yum install ruby-devel zlib-devel
I'm trying to deploy my Rails 4 app on Azure VM running Ubuntu 14.04.
Here's a logfile, atomic fails to install. ruby-v gives me ruby 2.0.0p451
Any ideas how to fix that?

Your gems are using ruby1.9.1 and you are missing dev files.
So install that using this command
sudo apt-get install ruby1.9.1-dev
If you are not sure about your ruby version you can use this command
sudo apt-get install ruby-dev
Make sure you also have the build-essential package installed. You can check using dpkg -l | grep build-essential or simply run sudo apt-get install build-essential.
Personally I tried lots of things before realizing I was missing the above mentioned package.
Tried to install pg gem I got the next error:

Already tryed to solve using
$ sudo apt-get install postgresql-client libpq5 libpq-dev
then:
$ sudo gem install pg
That is because you have not set the write permission to the directory,try:
chmod +777 /var/lib/gems/1.9.1
You need to install the -dev part of the Ruby package. Something like:
sudo apt-get install ruby1.9-dev
should give you the parts of Ruby necessary to compile binary extensions.
Good luck!
This help me:
sudo apt-get install rails
I got almost the same problem.
I use this to solve it.
$rvmsudo gem install pg

mkmf is part of the ruby-dev package if I'm not mistaken. Try:
sudo aptitude install ruby1.9.1-dev
Of course you may be better off installing ruby through RVM :)
For ubuntu 13.04, this is what worked for me:
sudo apt-get install ruby-dev
try
rvm all do gem install nokogiri
