Ruby nubie on OSX - can't get beyond rake db:migrate - get [BUG] Bus Error

Question

Original problem:

I'm (a newbie to ruby) using RVM to manage my ruby on Mac OSX 10.6

Here's my mac OX info:

I'm following a tutorial trying to get to the actual rails building part, and I'm fine up to here:

$ rails generate scaffold User name:string email:string

but am constantly getting the following error when I type this:

$ rake db:migrate

I don't know if the problem is the version of sqlite3, or ruby 1.9.2p180 - I've tried looking for this error using google and this is all I come up with https://redmine.ruby-lang.org/attachments/1505/ruby-1.9.2-bug.txt

I don't know how to interpret the errors below as I'm just figuring out how all the pieces fit together.

thank you for any pointers or help identifying the source of the error

The error message:

$ rake db:migrate --trace

Abort trap

EDIT: Answer found:

The problem was I was using an old (2007!) mac architecture - MacBook Core Duo (not to be confused with Core 2 Duo) which is 32 bit, NOT current 64 bit, and the current version of sqlite3 recommended in this tutorial (gem 'sqlite3-ruby', :require => 'sqlite3') did not work with the rest of my Gems. I uninstalled sqlite,

gem uninstall sqlite3 sqlite3-ruby
gem pristine --all  // not sure if necessary, suggested in comments

edited my Gemfile to:

gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'

then

Bundle install
rake db:migrate

and it works! So far.

I found the suggestion by Josh Crews to use an earlier version of sqlite3 - even though he was using it on Leopard, with ruby 1.8.7.

+1 for sticking with the problem! – the Tin Man Apr 14 '11 at 19:07 — the Tin Man, Apr 14 '11 at 19:07

OK, let's see if we can get your config straightened out.

You're using RVM, and a current rev of Ruby, so gather even more info about your RVM environment. Type rvm info and add that output to your original question by editing it. That will tell us more about what RVM knows.

Here's some questions:

Did you previously have Leopard installed, with RVM, then switch to Snow Leopard? If so, your Ruby would be compiled for 32-bit, but any native drivers compiled since then would be 64-bit which can cause real weird behavior. Fixing that takes a couple commands and some recompiling but it isn't overly painful.
Did you install Apple's XCode from the Snow Leopard DVD, or as a fresh install directly from Apple's XCode site? The version of XCode on the Snow Leopard was buggy and shouldn't be used. You can download a free copy from Apple's site. It's a big download.
Is your RVM current? Periodically run rvm get update. That might not help this particular problem, but it can fix some oddities. Use rvm -v to check the version. v1.5.2 is current as of today.

Some of the info at sqlite3-ruby can't make on rvm 1.8.7 might help.

EDIT:

A couple things stand out from your rvm info:

Your version of Ruby 1.9.2 is p188. p180 is the current stable version if I remember right, at least it is according to what RVM knows: rvm list known shows its list. That might cause problems with drivers that haven't been tested together. You might want to consider installing the current "1.9.2". RVM has a nice upgrade command that will let you install and copy your gems between versions of Ruby, so try rvm upgrade 1.9.2-p188 1.9.2-p180, then try running your app and see if SQLite is still being uncooperative.
Your version of Ruby 1.9.2-p188 is compiled as 32-bit. Your rvm info shows "i386-apple-darwin10.0" in several places. A 64-bit Ruby would show: "x86_64-darwin10.6.0". You can easily recompile a Ruby version by telling RVM to uninstall it, then install it again, i.e. rvm uninstall 1.9.2p188 && rvm install 1.9.2p188 should do it. Then you'll need to rebuild your gems that have native drivers: gem pristine --all will rebuild all installed gems.

thanks for the reply @theTinMan - 1. I only installed RVM once I upgraded to Snow Leopard / 2. I think I downloaded the xcode from the apple site / 3. I am using rvm v 1.5.2 - up to date — Mac Duck, Apr 07 '11 at 15:51
HI TinMan I was using XCODE 3.4 but downloaded and installed Xcode 3.2.6 and iOS SDK 4.3 - still get the same error. I also have ruby-1.9.2-head and ruby-1.9.2-p180 running using RVM - still get the same abort bus error — Mac Duck, Apr 14 '11 at 17:02
correction I'm using ruby 1.9.2p188 (2011-03-28 revision 31204) [i386-darwin10.6.0] — Mac Duck, Apr 14 '11 at 17:04
Also I'm using a 2 ghz intel core duo macbook - which IS only 32 bit. See the annoying thing is I know I had ruby working once.. but I think I was using the default from xcode. It's weird that using RVM would screw things up. I just don't know which variable to fix here. — Mac Duck, Apr 14 '11 at 17:08
I really doubt it's RVM. A way to locate the problem is to install the same version of Ruby from source using `--PREFIX=$HOME/opt` as the install directory. Add the path to the Ruby binary when it gets done, and try running the same commands you're having problems with. You'll have to install your gems/rails again, but that's easy once the path is pointing to the newly install Ruby. RVM only touches the PATH and environment and tweaks a couple `#!` lines if I remember right. It doesn't do any skanky black magic. Also, did you contact RVM's author about this? `rvm -v` shows his email. — the Tin Man, Apr 14 '11 at 17:56
HI TinMan the problem was the most recent version of sqlite3 doesn't work on Macs with 32bit architecture - I edited my question with more details. Thanks for your help. BTW I tried getting on irc to chat with the author - but had trouble getting mick nickname verified. Bewildering. I don't have that problem with otehr irc channels. — Mac Duck, Apr 14 '11 at 18:20
