I tried to install Rails on OS X Lion using the following command in Terminal:
sudo gem install rails
But I am getting the following error:
Building native extensions. This could take a while...
ERROR: Error installing rails:

Any help would be appreciated.
First install the Command Line Tools in the latest Xcode-Version.
and then run sudo gem install rails
To install Command Line Tools, go to XCode Preferences > Downloads.

Here is the code I put in and then the error followed: I am currently figuring out rails headers and see what could be happening. I follwed this article https://gorails.com/setup/ubuntu/16.04
and this article: http://ryanbigg.com/2014/10/ubuntu-ruby-ruby-install-chruby-and-you
and nothing.

Im also come up with this issue where I installed ruby environment manager rvm/ rbenv using sudo command.you can reinstall your ruby environment manager and avoid using sudo command or else all your gem installations would need sudo commands which you should avoid to prevent conflicts in the future.

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 is a couple of topics about that, but the reason I create a new one is that it still doesn't work for me ...
So here is my configuration :
ruby -v : 1.8.7
gem -v : 1.8.21
And when I try to make
sudo gem1.8 install rails
I have the following error :
Building native extensions. This could take a while...

I'm running on Debian 6.0.4 Squeeze.
Thanks in advance for your answers !
You don't have make command, as your output says. In debian install package build-essential
I think gcc or c-compiler isn't install or not writen in environment path, I've got same problem while installing rails, but after Install gcc, I can install rails very well.
On Ruby 1.8.7 and rails 2.3.5 I get:
gem install rmagick

on Ubuntu/Debian you would need to install:
sudo apt-get install libmagickwand-dev
on RedHat/Fedora/CentOS:
yum install ImageMagick-devel
To install rmagick with the gem system, you must have "imagemagick" on your system. The following error line says that rmagick failed to build because the native extension (imagemagick) does not exist on your system.
ERROR: Failed to build gem native extension.
On OSX, you can use brew (the best way in my opinion) to install imagemagick. Once brew is installed :
brew install imagemagick
gem install rmagick
On Mountain Lion (OSX), after:
brew install imagemagick
it may be necessary to force the re-creation of some symlinks manually before being able to install the rmagick gem.
> brew link -f jpeg
> brew link -f libpng
> brew link -f freetype
> brew link -f imagemagick
On fedora make sure you have ImageMagick-devel installed.
for this command i got this error "sudo gem install sqlite3-ruby"

sqlite3 --version 3.6.12
If you have ports installed try:
port install sqlite
Or if you are using brew:
brew install sqlite
Does that fix it?
