Problem starting WEBrick

rubyonrails-talk
1

Ruby nuby here, but this seems like I overlooked something. I'm running Rails 2.1.1 on Mac OS Leopard.

I go into terminal and create an app:

  rails whatever

I move into my app and try to start WEBrick

  cd ./whatever   ruby script/server

And I get the following error:

  Rails requires RubyGems >= . Please install RubyGems and try again: http://rubygems.rubyforge.org

However, I already have RubyGems 1.3.0 installed, so I'm not sure where this issue comes from. The fact that the error also doesn't denote a RubyGems version seems strange.

Any ideas? I'm really stuck on this and can't find anything via Google or the forum.

Rails checks the RubyGems version using Gem::RubyGemsVersion. I launched IRB and queried the version:

$ irb

Gem::RubyGemsVersion => “1.2.0”

What does yours report?

Based on the error message that you received, I expect it to report an empty string.

I’m on Mac OS X 10.5.5 using the built-in Ruby, 1.8.6 p114.

$ ruby -v ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]

What versions of OS X and Ruby are you running? Did you install Ruby from source or via MacPorts or Fink?

I believe I'm running Ruby 1.8.7 from source. Again, being a complete nube, I really have no clue which file(s):

Macintosh-3:~ johnclaus$ ruby --version ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9.4.0]

I'm also running Leopard 10.5.5.

Since rails comes in as a gem, it's doubtful that you don't have rubygems installed. It is possible that you have ruby and gems installed in non-standard locations.

On my mac:

which ruby => /opt/local/bin/ruby which gem => /opt/local/bin/gem which rails => /opt/local/bin/rails

ruby --version => ruby 1.8.7 (2008-08-11 patchlevel 72) [powerpc- darwin9] gem --version => 1.3.0 rails --version => Rails 2.2.0

NOTE: This is not what ships on the mac - that's all found below:

/System/Library/Frameworks/Ruby.framework/...

You would probably do best if you go to: http://www.rubyonrails.org/down and follow the directions there.
