Gem error on "require 'rubygems'"

[Luc Juggery]

Hello RubyComminity !!!!

I have decided to move to ruby to make the util script I usually do in Perl.
I need to create a graph from an XML file.
For this, it seems that I can use gruff and magic/xml (not sure this
is the best choice as I am not familiar with those libs).

I have installed the gruff gem, that went fine.
Regarding magic/xml I have unzip the install and copy the folder in
"C:\ruby\lib\ruby\1.8" (is that enought ???)

Then I tried the gruff example:

------

#!/usr/bin/ruby

require 'rubygems'
require 'gruff'

g = Gruff::Line.new
g.title = "My Graph"

g.data("Apples", [1, 2, 3, 4, 4, 3])
g.data("Oranges", [4, 8, 7, 9, 8, 9])
g.data("Watermelon", [2, 3, 1, 5, 6, 8])
g.data("Peaches", [9, 9, 10, 8, 7, 9])

g.labels = {0 => '2003', 2 => '2004', 4 => '2005'}

g.write('my_fruity_graph.png')

-------
But I get the following error.....

Gem::LoadError: Could not find RubyGem hoe (>= 1.1.2)

Do you have an idea of what went wrong ?
Also, I have to install all the gem locally as I am behind a proxy (do
not know if this can be linked)

Thanks a lot,

Luc

Do you have RubyGem Hoe 1.1.2 installed? I.e.,

Hello Bill,

I guess it should not installed......

C:\temp\Ruby\graph>"c:\ruby\bin\ruby.exe" "c:\ruby\bin\gem" list hoe
*** LOCAL GEMS ***
C:\temp\Ruby\graph>

I have installed it and a couple of other gems required.
Then I tried to installed RMagick and got the following:

-----
C:\Documents and Settings\x0001027\Desktop>"c:\ruby\bin\ruby.exe"
"c:\ruby\bin\gem" install rmagick-1.14.1

The "rmagick" gem is for *nix installs. Use the rmagick-win32 gem for Win32.
