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

I know there are tons of questions like this one, but I looked at all of them I could find and none of them worked.
I just installed CentOS today, so I'm still getting used to how things worked. I installed ruby with this command:
sudo yum install ruby

I ran sudo gem update and sudo gem update --system, but both of them gave an error too. For sudo gem update, the error message was really long so I put it in a pastebin to not clutter things which you can find here. For sudo gem update --system here is the error message:'

What else do I need to do/install? You can ask me if I installed something in the comments.
I had same issue today.
After some curses, I noticed that in gem list there was rubygem-update, but with another path... not in /usr/share/gems/ but in /usr/local/share/gems
So I did
sudo ln -s /usr/local/share/gems/gems/rubygems-update-3.1.4/ /usr/share/gems/gems/rubygems-update-3.1.4
And everything was fine.

Make sure that `gem install json -v '1.8.6'` succeeds before bundling
Kindly send me some suggestions,Thanks in Advance.
If you have a Mac or Linux machine try the following command:
sudo apt-get install ruby-dev
If that fails, what is your output for:
gem install json -v '1.8.6'
(please copy and paste all the output).

I'm not sure what will fix it for Mac, but people had positive experiences with brew install ruby.
If anyone facing this error with Mac OS Big Sur, please update the ruby version to atleast 2.7. I am using rvm to resolve this issue.
First checked the ruby version and rvm list
if rvm not install then install rvm
My ruby version is ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]. And my gem version is 2.5.1
I want to install rails, but when I try sudo gem install rails
