Failed to build native gem extension - Rails Install

Question

I followed the instructions on the thread here but I still have the following error message:

Ayman$ rails -v
Rails is not currently installed on this system. To get the latest version, simply type:

$ sudo gem install rails

You can then rerun your "rails" command.
Ayman$ gem install rails

Ayman$

I am on the latest version of gems, running ruby 2.0.0, and Mac 10.8.

Any clue on what I am doing wrong?

Update

So I installed Xcode Command Line Tool per the following and am still recieving the following error message:

Ayman$ sudo gem install rails
Building native extensions.  This could take a while...
ERROR:  Error installing rails:

Ok so I installed the Command Line Tool, restarted my computer, and went through the steps in the thread linked above and I'm still getting the same error. What gives? — aalab002, Jan 19 '14 at 09:43
You're not using `sudo` for your command, you really should as you won't have the necessary permissions otherwise. — Alex Siri, Jan 19 '14 at 09:53
Just tried running `sudo gem install rails` and I came back with the same error message — aalab002, Jan 19 '14 at 09:56
You probably need to symlink gcc? What does `which gcc` return? — revolver, Jan 19 '14 at 11:41

I solved the problem.

Turns out I was using an outdated version of gems.

Once I upgraded my gems to the latest version it worked fine.

Thanks everyone!

Try rvmsudo to use your rvm and have root privileges, maybe like this:

rvmsudo gem install rails

EDIT

I meant 'rvmsudo', not 'sudorvm'. Sorry for the mistake, I was on a phone.

`Ayman$ sudorvm gem install rails -bash: sudorvm: command not found` – aalab002 Jan 19 '14 at 16:01
Just tried it with `rvmsudo` instead of `sudorvm` and that worked and prompted for a password and started initializing but then returning the same error message as before. – aalab002 Jan 19 '14 at 16:06
I just tried it again and now I get `ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError) no such name (http://api.rubygems.org/quick/Marshal.4.8/minitest-4.7.5.gemspec.rz)` – aalab002 Jan 19 '14 at 17:39

There is always rbenv where you can skip all the hassle of sudo and permissions. Everything local to the user. Why rbenv?

brew update
brew install rbenv ruby-build

# if you dont have the init in your profile run the following:
echo 'eval "$(rbenv init - --no-rehash)"' >> ~/.bash_profile
source ~/.bash_profile

# install a ruby
rbenv install 2.1.0
# you need to rehash after installing a ruby version or a global gem
rbenv rehash
# this will set 2.1.0 as your default ruby version in shell
rbenv global 2.1.0

# now try installing rails
gem install rails bundler --no-ri --no-rdoc
rbenv rehash

I downloaded rbenv but can't seem to find the command to install rails. All docs tell me to simply run `gem install rails` and that brings back the same error message. – aalab002 Jan 19 '14 at 16:10
when I try `rbenv install rails` it tells me `ruby-build definition not found: rails` so I list available versions: `Ayman$ rbenv install --list Available versions: 1.8.6-p383 1.8.6-p420 1.8.7-p249 1.8.7-p302 1.8.7-p334 1.8.7-p352 1.8.7-p357 1.8.7-p358 1.8.7-p370 1.8.7-p371 1.8.7-p374 1.8.7-p375 1.9.1-p378 1.9.1-p430 1.9.2-p0 1.9.2-p180 1.9.2-p290 1.9.2-p318 1.9.2-p320 1.9.2-p326 1.9.3-dev 1.9.3-p0 1.9.3-p125 1.9.3-p194 1.9.3-p286` – aalab002 Jan 19 '14 at 16:17

@aalab002 did you install a ruby yet with rbenv? You also need to do `brew install ruby-build` so you can build rubies. Once you have that, try running `rbenv versions` if you dont see a ruby, try `rbenv install 2.1.0` then `rbenv rehash` then `rbenv global 2.1.0` followed by `gem install rails` and finally another `rbenv rehash` – chrisan Jan 19 '14 at 16:52
@aalab002 I updated the original post with instructions – chrisan Jan 19 '14 at 16:56
I updated the original question with my terminal log. The problem appears to be related to my permissions: `Ayman$ gem install rails bundler --no-ri --no-rdoc ERROR: While executing gem ... (Errno::EACCES) Permission denied - /Users/Ayman/.rvm/gems/ruby-2.0.0-p353/gems/atomic-1.1.14/test/test_atomic.rb` – aalab002 Jan 19 '14 at 17:21
I tried `sudo gem install rails` again now the error message has changed to: `Ayman$ sudo gem install rails ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError) no such name (http://api.rubygems.org/quick/Marshal.4.8/minitest-4.7.5.gemspec.rz)` – aalab002 Jan 19 '14 at 17:26
