Install Rails from terminal

Rails
1

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…

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

tried install MYSQL and i got the same error message.

$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql –
–with-mysql-config=/usr/local/mysql/bin/mysql_config

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