Net::HTTP.post_form missing method error

Ruby
1

I had some code that used to work and now all of a sudden it stopped
working. Here is the minimal code to illustrate the problem:

#!/usr/bin/ruby
require ‘net/http’
require ‘uri’
parms = {:client=>“safari”, :rls=>“en”, :q => “myquery”,
:ie => “UTF-8”, :oe => “UTF-8”}
url = “Google”

res = Net::HTTP.post_form(URI.parse(url), parms)

print res.body
print

The code fails with this error:
./foo.rb:8: undefined method `post_form’ for Net::HTTP:Class
(NoMethodError)

However, my code is almost identical to the example at:
http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html#M001204

…which presumably should work.

This is on a mac. I tried it on a windows box and it failed with the
same error. I tried it on a linux box and it worked (the request format
isn’t quite right, but something came back from the server and was
printed out, so for the purposes of this post, it “works”).

Anyone have any ideas as to why? Apparently I have the Net::HTTP class
but it doesn’t have the post_form method in it…anymore…

Hope someone can help.

What version of ruby are you using on each platform?

Mac OX 10.4: ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]
Linux: ruby 1.8.3 (2005-09-21) [i686-linux]
Win XP SP2: ruby 1.8.2 (2004-12-25) [i386-mswin32]

Again, it works on linux but not on Mac or Win.

Because, I believe, that method was added in 1.8.3.

Duh. Thanks. Can someone tell me the least painful way to upgrade my
Ruby installation?
I am using Locomotive on the mac for Rails development, but there is
also a ruby in /usr/bin.

Locomotive has Ruby and all the gems self-contained, inside the
Locomotive.app icon/folder/thing. If you are going to continue using
Locomotive, make sure you update the one inside that directory, and NOT
the one in /usr/bin, which isn’t used in this env. Sorry, I don’t know
how to do that, I would check on the locomotive site itself.
