Error trying to run rails server

I am trying to get a basic Rails application to run on my Mac OS X 10.6.5. I created a new app called demo (rails new demo), then went into the demo directory and tried to start the app with rails server. Here is the error message I received: "/Users/dpetrovi/.gem/ruby/1.8/gems/sqlite3-ruby-1.3.2/lib/sqlite3/sqlite3_native.bundle: [BUG] Segmentation fault ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10]

Abort trap"

I checked bundle install in the demo folder:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

Ruby, RubyGems, and sqlite3 were installed using MacPorts. Then I used gem to try to install the sqlite3-ruby interface. (sudo gem install sqlite3-ruby). Here is where I first noticed something could be off:

Successfully installed sqlite3-ruby-1.3.2
1 gem installed
Installing ri documentation for sqlite3-ruby-1.3.2...

No definition for libversion

Enclosing class/module 'mSqlite3' for class Statement not known
Installing RDoc documentation for sqlite3-ruby-1.3.2...

No definition for libversion

Enclosing class/module 'mSqlite3' for class Statement not known

I had rails running well on my system a few months ago, so I figured maybe I had some duplicates and it was trying to use the wrong one. I ran: for cmd in ruby irb gem rake; do which $cmd; done and got:

/opt/local/bin/ruby
/opt/local/bin/irb
/opt/local/bin/gem
/opt/local/bin/rake

Checking where sqlite3 also gets me: "/opt/local/bin/sqlite3" so they all seem to be in the right place. Obviously /opt/local/bin is in my system path.

If I check gems server, it shows that I have installed sqlite3-ruby 1.3.2 gem. Not sure what the problem could be?

I am using ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10]. Macports claims this is the latest (although ive seen 1.9.1)

One more thing-- in irb, I tried to check which version of sqlite3 my sqlite3-ruby is bound to, but I can only get this far:

:irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'sqlite3'
/Users/dpetrovi/.gem/ruby/1.8/gems/sqlite3-ruby-1.3.2/lib/sqlite3/sqlite3_native.bundle: [BUG] Segmentation fault
ruby 1.8.7 (2010-12-23 patchlevel 330) [i686-darwin10]

Abort trap

Any suggestions? Im hoping I overlooked something obvious. Thanks

Have you upgraded to Snow Leopard recently? If so, you need to reinstall MacPorts and all the ports installed with it.

I recommend using RVM instead MacPorts installed ruby.

Definitely use RVM as mentioned above and then try this in your app's directory:

rm -rf .bundle && bundle install

i had the same problem. here is how i resolved it.

removed the gem sqlite3-ruby did bundle install reinstalled the gem recreated the rails app

now webrick works fine.
