it looks like you have `rvm` installed. is there a particular reason you're doing `sudo gem install` instead of `gem install`? — , Aug 11 '13 at 03:53
I use _sudo gem install_ 'cause if I just use _gem install_, it will prompt there's some permission issue. — Capt. Michael, Aug 11 '13 at 04:41
I don't know where the mkmf.log is, I use whereis command cannot find it, could you please give the path? Thanks! — Capt. Michael, Aug 11 '13 at 04:44
Check this thread: http://stackoverflow.com/questions/11802918/error-failed-to-build-gem-native-extension-when-installing-rails-on-mac-mountia It discusses a problem very similar to yours — amb110395, Aug 11 '13 at 04:49
@amb110395 Yes, I tried, but it doesn't work, the same error still prompts. And I found it should be gem's issue, 'cause even I use _gem update_, the same problem will also happen. — Capt. Michael, Aug 11 '13 at 05:09
@Zabba It's XCode 4.6.3. This is my new Mac, so every software is the latest version. — Capt. Michael, Aug 11 '13 at 05:11
Did you install the xcode Command Line Tools (http://stackoverflow.com/a/17775189/382818) then restart terminal — Zabba, Aug 11 '13 at 05:13

I ran into this issue today and it seems that my download of ruby-2.0.0 did not work properly. I would recommend trying rvm reinstall 2.0.0 followed by gem install rails.

I had to `rvm get stable`, followed by `rvm reinstall 2.0.0`, but this did the trick for me. Thanks. – Ben Hull Jan 15 '14 at 11:16

Finally, I got the solution! Run rvm implode，and use rm to delete /etc/rvmrc and ~/.rmvrc, restart your mac, and you can use gem install rails to install rails successfully.

Be careful with this - rvm implode removes all rvm gemsets from your system, so if you already have projects running on RVM this will *reset* them. – Arrel Dec 18 '13 at 03:41

First I installed gcc via homebrew:

installing gcc on mavericks using brew

brew tap homebrew/dupes brew install apple-gcc42

Then I symlinked the newly installed apple-gcc42 into my /usr/bin folder

cd /usr/bin

sudo mv gcc gcc_mavs sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 gcc

I've just been having the same issue on El Capitan. For anyone else coming across this on El Capitan, try following these instructions, but skip `sudo mv gcc gcc_mavs`. – Barnaby Jul 29 '16 at 02:49

I had this same error when running against ruby-2.0.0-p195, but updating to ruby-2.0.0-p247 (the current RVM default for 2.0.0) fixed it.
