Okay so I’m new to ruby and rails. This is probably a very easy  
question. So, I’m trying to run Webrick but it tells me that I need to  
install gems.  
This is what I keep getting:  
Macintosh:contactlist sue$ ruby script/server Webrick  
Rails requires RubyGems \>= . Please install RubyGems and try again:  
[http://rubygems.rubyforge.org](http://rubygems.rubyforge.org)

So I keep trying to update/ install ruby. I think the problem is that it  
is not installing the Installing rubygems-1.3.4 ri into  
/Library/Ruby/Gems/1.8/doc/rubygems-1.3.4/ri stuff. I honestly have no  
clue. Please help:

Sue, try doing the following Rubygems:

sudo gem update --system

Furthermore, you should install all your gems using the following:

sudo gem install

Good luck,

Thanks for answering.  
Which Gem would I need to install if Webrick isn’t working?

Sorry, the current version of rubygems is 1.3.4. You can adjust the  
commands I suggested from 1.3.1 to 1.3.4.

Try typing the following to determine which version of rubygems you  
have installed:

gem -v

The current version is 1.3.1

I suspect you might have competing versions of rubygems or ruby  
installed. You can find out which path is being used for each by  
typing:

which ruby  
which gem

Depending upon what you find, you may need to re-install rubygems from  
scratch. If your gem path and ruby path vary (for example, ruby is /  
usr/bin/ruby and rubygems are /usr/local/bin/gem) then I’d suggest  
reinstalling rubygems like so:

curl -O  
[http://rubyforge.iasi.roedu.net/files/rubygems/rubygems-1.3.1.tgz](http://rubyforge.iasi.roedu.net/files/rubygems/rubygems-1.3.1.tgz)  
tar xzvf rubygems-1.3.1.tgz  
cd rubygems-1.3.1  
sudo /usr/bin/ruby setup.rb

That last line should mirror the full path to the ruby executable. So  
if when you typed ‘which ruby’ it returned /usr/local/bin/ruby, then  
you’d want to use that instead:

sudo /usr/local/bin/ruby setup.rb

Hope this helps.

Sue, Webrick should have been installed with the Ruby installation.  
Also,  
you  
should be able to do the following:

cd contactlist  
ruby script/server webrick

Note: The ‘w’ in Webrick above should be in lower case when invoking on  
the  
command line.

Good luck,

-Conrad
