twitter ruby gem not working

[stevekl]

hi guys,

new to ruby and rails. read a good chunk of simply rails 2 and i want to play around with the twitter api. instead of parsing it all myself i saw there was a twitter ruby gem on rubyforge

i'm on ubuntu linux. i ran
sudo gem install twitter
and
sudo install twitter

when i run the code:

require 'rubygems'
require 'twitter'

#searches all tweets for httparty
Twitter::Search.new('httparty').each { |r| puts r.inspect }

i get the error:
./twitter.rb:5: uninitialized constant Twitter (NameError)
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require'
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in `require'
from -:2

any idea of what i'm doing wrong? thanks!

Hi stevekl, welcome to the forums,

If you do "$ gem list", is twitter there?

[stevekl]

hey,

twitter is listed there. any insight?

thanks!

[Mittineague]

I haven't installed the twitter gem to try it, but I did download it and take a quick look. Several of the files in the examples folder start with

require 'rubygems'
require File.join(File.dirname(__FILE__), '..', 'lib', 'twitter')
config = YAML::load(open(ENV['HOME'] + '/.twitter'))
 
twitter = Twitter::Base.new(config['email'], config['password'])

But your code

require 'rubygems'
require 'twitter'
 
#searches all tweets for httparty
Twitter::Search.new('httparty').each { |r| puts r.inspect }

looks similar to
search.rb

require 'rubygems'
require File.join(File.dirname(__FILE__), '..', 'lib', 'twitter')
 
Twitter::Search.new('httparty').each { |r| puts r.inspect,'' }
.....

Are you sure your path to "twitter" is correct?

[stevekl]

it seems like my path to twitter is correct, because it's not throwing an error on the require line. while if i put require 'twitter-fake' or something that doesnt exist an error is thrown. but, also i can't be positive because i don't know where the ruby gem installer installs the twitter lib.

[Mittineague]

I have Windows OS, my "plugin" gems are in the ["my app"]\vendor\plugins\ folder. The Ruby gems are in ["ruby install dir"]\lib\ruby\gems\1.8\gems\

[stevekl]

thanks for your help so far

so i found it's located at: usr/lib/ruby/gems/1.8/gems/twitter-0.3.7/
still not sure how to get this working though.

[Mittineague]

I'll install the gem (it may take a while) to see if I can get it to work and post back.

[stevekl]

that'd be great..thanks so much

[Mittineague]

I didn't try any code yet. But I did finally finish installing (darn bulk update arrgghh). There were a few dependencies, did you get them too?

Without modifying any files or using any configuration info (vanilla install), I ran the search.rb file in the console

>ruby lib\ruby\gems\1.8\gems\twitter-0.3.7\examples\search.rb

and got

Mittineague,

I've installed the twitter gem on my new acer aspire one netbook (what a sexy little machine she is...) and our search.rb code works fine. So, it's got to be some issue (dependency maybe, will investigate later) on the other machine. Now that I know it's machine specific I'll be able to investigate further when I have the time.

Thanks again for all your help!

Just to solve that tricky thing which I ran into myself, it works if you do like this:

require 'rubygems'
require 'httparty'
require 'mash'
require 'twitter'
require 'twitter/search'

I'll have a talk with the gem's programmer how to fix that situation.
