Hi, did you add the rack gem to your gem file?

================================================

I read the release message → “Rails 3.0: Second beta release” → from

Note that Ruby 1.8.7 p248 and p249 has marshaling bugs that crash both
Rails 2.3.x and Rails 3.0.0. Ruby 1.9.1 outright segfaults on Rails
3.0.0, so if you want to use Rails 3 with 1.9.x, jump on 1.9.2 trunk for
smooth sailing.

================================================

and, someone suggested that I delete config.ru or change nginx.conf as
below :

rails_env development; → rack_env development;

server {
listen 3001;
server_name horn.local;
root /Users/shajun/project/horn/public; # <— be sure to
point to ‘public’!
passenger_enabled on;

    "rails_env development; -> rack_env development;"

 }

but I could not decide this question.

================================================

Thank you very much again! Conrad

all right !

Ruby version 1.8.7 (i686-darwin10.0.0)

I’m having this same issue, but on Apache with Rails 3 Beta 3. I noticed
that your Ruby version is now 1.8.7 and not 1.9.2. I’m trying to figure
out how to get past the “no such file to load – rack” issue while
keeping Ruby 1.9.2.

I tried your approach of changing passenger_ruby to the home directory
instead of using the “ruby 1.9.2-head” directory but my home directory
is empty. I installed RVM via git so the closest matching folder I can
find is in /root/.rvm/src/rvm/bin/ but I don’t have a passenger_ruby
file in there.

I’ve tried everything I’ve found on Google as possible solutions and
can’t get it to work.

Any advice?
Thanks
Bobby

nevermind, got it working. Once I fully understood all of these
directions: http://rvm.beginrescueend.com/integration/passenger/ I got
it working. Needed to make sure that PassengerRuby was pointed to
something like: /home/wayne/.rvm/bin/passenger_ruby instead of the RVM
ruby
