I have been having trouble install Rails from the terminal on my new MacBook. I have tried to find a solution on both google and youtube, but I have not find a solution to the problem

$ 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.

$ sudo gem install rails Building native extensions. This could take a while... ERROR: Error installing rails:   ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/json-1.6.6 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/json-1.6.6/ext/json/ext/generator/gem_make.out

"hi,make sure that uve install ruby-dev package"

I have ruby installed on my computer already, gem as well just not rails. That is where I am having my problems at.

I might been having an issue with gems and where it is installed. I just tried install MYSQL and i got the same error message.

Read the suggestion more carefully, it says you need the package ruby-dev installed.
