I was trying to install Sass. Went through this guide to install Ruby which Sass website told is a pre-requisite
https://www.digitalocean.com/community/tutorials/how-to-install-ruby-and-set-up-a-local-programming-environment-on-ubuntu-16-04
Looks like it went well
$ ruby -v
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
Now I am stuck at this point. I am not sure how to proceed further. I am using Ubuntu 16.04
$ sudo gem install sass

What should I do now ? Please help.
sudo apt-get install ruby-dev
The above command fixed it for me.
Try installing libffi-dev
sudo apt-get install libffi-dev

You are getting this error because there is no ruby development environment installed. Development environment is needed to compile ruby extensions,
You should install development first using command below:
$ sudo apt-get install ruby-dev
I had a similar issue and i solved it by installing ruby-dev:
sudo apt-get install ruby-dev

You can try with this
sudo apt-get install build-essential
and after it
sudo gem install rails

I am using fresh rvm and ruby 1.9.3 and have same trouble only with json gem.
The error occurs when I try to execute:
gem install json
If I add sudo everything is ok, but I cannot (and shouldn't) use sudo with rvm commands.
sudo apt-get install ruby1.9.1-dev
may fix it .Cheers !
Try running below commands(works for ubuntu 14.04):
$ sudo apt-get install libgmp3-dev
and then install json
$ gem install json

For me this worked (a solution from #mjgpy3)
sudo apt-get install ruby-json

gem is installed:

ruby also fine:
ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
Are you sure you have make, gcc et al?
$ sudo apt-get install build-essential
Does "which make" point to anything?
apt-get install build-essential zlib1g-dev libssl-dev libreadline5-dev
This should be everything you need to get passenger to build
