I just changed my iMac G5 to a MacBook. There are lot of instructions on installing Ruby and Rails on a Mac on the net, some of them not quite up to date. Here is what I find to be the easiest way to do it.
- Pop your Mac OS X install disc 1 and install the xcode tools. (this installs an old version of ruby)
- Download and install MacPorts
- open terminal:
sudo nano /etc/profile
Prepend /opt/local/bin: to PATH, so it reads:
This is to make sure the new version we are about to install will get used instead of the old one.
- Make sure MacPorts is up to date:
sudo port selfupdate
- Install ruby and rubygems:
sudo port install ruby sudo port install rb-rubygems ruby -v
This last command should give 1.8.6. If you see 1.8.2, this means it is still using the version installed from the OS X cd. Make you correctly updated your PATH.
- Install Rails:
sudo gem install rails -y
You might also want to install subversion right now using ports:
sudo port install subversion
(Note: at the time of writing, Rails is at version 1.2.3 and Ruby at 1.8.6. )
