rails server

I'm seeing the same issue. Using the rails command from inside a new rails 3 app, and I get ton of warning output. It's basically telling me all the gemspecs for all the gems rails requires are invalid, same warnings over and over:

WARNING:  #<NoMethodError: undefined method `>' for nil:NilClass>
WARNING:  Invalid .gemspec format in '/usr/local/Cellar/ruby/1.9.1-p378/lib/ruby/gems/1.9.1/specifications/abstract-1.0.0.gemspec'

I'm using homebrew with ruby 1.9.1p378. I installed rails 3 using gem install rails3b and gem install rails --pre
I attached the STDERR output I'm getting.

Looks like this is an issue with rubygems 1.3.5 and ruby 1.9.1

Is theere a solution?

The problem seems to stem from the fact that bundler requires 'rubygems/specification'. I can replicate the problem outside of rails too. Try this in irb:

require 'bundler'

I assume then there is no user fix for this. I should probably just wait for the public release of Rails 3. Right?

It's more annoying than anything. Interestingly, I can use rackup instead of rails server and I get no error output.

`rackup -p 3000`

I too get this annoying spam when I start up the server. More of a you-upgraded-rubygems-and-you-shouldn't-have issue, methinks. But doesn't some gem require you to have 1.3.5?

Ryan I think you are right.

Check out this Bundler issue: http://github.com/carlhuda/bundler/issues/#issue/24. I was able to get rid of the spam by following @sakuro's advice.
