Uninstall Ruby on Rails on Mac OS X 10.6

Question

I´m trying to get RoR up and running with mysql data base, but it seems to be impossible to me (i get an error when including the mysql gem). So i tried to do a lot of things over the console with no results and i don´t remeber what i have done.

So, i want to delete everything and start again from cero. How can i delete RoR from my Mac ?

Thanks!

What errors are you getting anyway? It's pretty straightforward to go about installing Rails on 10.6 using either MacPorts or Homebrew. — tadman, Apr 01 '11 at 14:21

The easiest way to get a basic RoR setup is to use Homebrew to install mysql and RVM to manage rails. If you follow the instructions below, including installation of RVM, you wont need to worry about already failed installations of ruby or rails because they'll basically install everything in it's own location and then repoint your environment to the new ruby and rails installation.

Visit https://github.com/mxcl/homebrew and read up on homebrew. You'll thank me later :)
Install homebrew with this:

ruby -e "$(curl -fsSL https://gist.github.com/raw/323731/install_homebrew.rb)"
Install XCode if you haven't already. Easiest way is to use the disk that came with your Mac.
Install git:

brew install git
Install RVM: (Optional, but great if you want to use Ruby on Rails with ruby 1.9.2). Again, read up on RVM: http://rvm.beginrescueend.com/ Follow the instructions here: http://rvm.beginrescueend.com/rvm/install/ AND DONT FORGET TO DO THE POST INSTALL!!!
Install 1.9.2 and set it to be the default:

rvm install 1.9.2

This will take a while

rvm --default use 1.9.2
Install Rails

gem install rails
Install mysql

brew install mysql

(When this is finished, you will need to initialize your database. The instructions will be given to you when the install finishes. If you skip this, your database won't work. If you closed your terminal and want to see the instructions again you can type "brew info mysql" and it will show them to you.)
Create your rails app:

rails new my_app

Also, if you have any troubles starting mysql, try: sudo chown -R $USER /usr/local — Mike Farmer, Apr 04 '11 at 15:49

Hi I had the same problem with the mysql gem and they way I succeeded was downgrading from ruby 1.9.2 to 1.8.7. I don't know which one are you using.

I uninstall ruby using port also.

Hope this could help.

Bye

To completely uninstall rails and all gems use this with sudo permissions:--

gem list | cut -d" " -f1 | xargs gem uninstall -aIx

depends on how did you install it. Or just remove folder – fl00r Apr 01 '11 at 14:01

There's a Ruby that ships with 10.6 that you shouldn't remove, but any you've added after the fact, either using `rvm`, `port` or `brew` can be removed using the respective package manager. – tadman Apr 01 '11 at 14:20
I just downloaded the version 1.8.7 from http://rubyonrails.org/download and install it from console. – mdaguerre Apr 01 '11 at 14:29
