Help with Ruby Gems

suelee · June 14, 2009, 11:17pm

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

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:

Installing rubygems-1.3.4 rdoc into
/Library/Ruby/Gems/1.8/doc/rubygems-1.3.4/rdoc
Macintosh:~ sue$ sudo gem install rubygems-update

Oh-no! Unable to find release notes!

RubyGems installed the following executables:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem

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.

suelee · June 15, 2009, 4:27am

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
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
