Quick Note On RVM+Ruby installation

Problem

I got rid of all the developer tools on my Mac to clean up the messed up environment from countless experiments.

sudo /Developer/Library/uninstall-devtools –mode=all

rm -f /Developer

These commands got rid of everything.

Then I got rid of MacPorts

sudo port -fp uninstall –follow-dependents installed

sudo rm -rf \>     /opt/local \
/Applications/DarwinPorts \
/Applications/MacPorts \
/Library/LaunchDaemons/org.macports.* \
/Library/Receipts/DarwinPorts*.pkg \
/Library/Receipts/MacPorts*.pkg \
/Library/StartupItems/DarwinPortsStartup \
/Library/Tcl/darwinports1.0 \
/Library/Tcl/macports1.0 \
~/.macports

Prerequisites

1Xcode – http://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12

Get this from the Mac App Store.

2. Command Line Tools For OS X – https://developer.apple.com/downloads/index.action?=command%20line%20tools

Command Line Toosl gives you gcc, the lexical parsers, linkers etc for compiling binaries.

3. Installed RVM with instructions from http://beginrescueend.com/

Installing Ruby

Before installing Ruby, install some additional packages, else you might find that some stuff don’t work after the installation. One example is irb

For simplicity sake, do this:

bash> for i in readline iconv ncurses ; do rvm pkg install $i; done

Install Ruby.

rvm install 1.9.3-head –with-gcc=clang –with-readline –with-iconv –with-ncurses

The “–with-gcc=clang” is a recommendation in rvm requirements. It’s for those who has a fresh Lion install with Xcode 4.2.

That’s it. Ruby done. You can now continue with Rails etc.
