I'm trying to install the yob pdf reader: https://github.com/yob/pdf-reader#readme
My script has the following code:
reader = PDF::Reader.new("1.pdf")
when I run that script I get the following error:
`initialize': wrong number of arguments (1 for 0) (ArgumentError)
Which doesn't make any sense because the directions say this should be done this way.
How do I solve this?
p.s.
gem list command produces:

You most likely have a gem version conflict. You can specify the version of the gem that you want to require, in case you have multiple versions installed:
require 'rubygems'
gem 'pdf-reader', "~> 0.10.0"
require 'pdf-reader'
Update
I would slap myself if I could. There's nothing wrong with your setup. The instructions to use PDF::Reader.new "my_file.pdf" are for the git version.
Check the examples directory for the version 0.10.0 to get examples of how to use the library.

Found the problem.
I had Jruby installed along with Ruby, so when installing the gem it will automatically install under the Jruby directory and later won't be found by Ruby removing the Jruby from PATH end variable solved the problem
I tried to add docx-html gem to my project and here's what I get while bundle install:
Bundler could not find compatible versions for gem "rubyzip": In
Gemfile:
zip-zip (>= 0) ruby depends on
rubyzip (>= 1.0.0) ruby
docx-html (>= 0) ruby depends on
docx (~> 0.1.0) ruby depends on
rubyzip (0.9.1)
Part of my Gemfile:
gem 'rubyzip'
gem 'zip-zip'
gem 'docx_replace'
I added the line gem 'zip-zip' by an advice from another StackOverflow question. If I exclude it, instead of bundle install error I get the following error while trying to start the server:
`require': cannot load such file -- zip
How do I get rid of these errors while keeping gem docx_replace?
I haven't yet figured out why, but for some reason changing Gemfile code to this worked:
gem 'zip'
gem 'docx_replace'
This is what I'm using: Windows 8. Cygwin32. Rvm version 1.25.27. Ruby version 2.1.2p95. Gem version 2.3.0. Drush version 5.9.
I'm totally new to all this so it's very possible that the explanation is something really simple.
I tried to use "drush omega-guard" from my drupal theme folder but got an error saying I had to install Bundler version 1.2 or newer. This is all fine since I hadn't installed bundle. But when I try to use the command "bundle install" I get this:
$ bundle install
-bash: bundle: kommandot finns inte
(Kommandot finns inte = Command not found.)
When I try using "gem bundler install" I get this:
$ gem bundler install
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command bundler
I also tried "gem bundle install":
$ gem bundle install
ERROR: While executing gem ... (Gem::CommandLineError)
Unknown command bundle
So I used "which bundle" and then used cd to get to that folder.
$ which bundle
/home/I/.rvm/gems/ruby-2.1.2/bin/bundle
I tried the same commands again, but from the other folder, and ended up with this:
I#I ~/.rvm/gems/ruby-2.1.2/bin
$ gem install bundler
ERROR: While executing gem ... (TypeError)

I#I ~/.rvm/gems/ruby-2.1.2/bin

EDIT: Since I asked this question I tried reinstalling ruby 2.1.2. The installation stuck on "#importing gemset" and after about 36 hours my computer was turned of due to a blackout. I therefore don't know if the reinstallation was completed or not. After that I also changed my gem version to 2.1.2 to match the ruby version. Theese things seemed to help and afterwards I could run both "gem install bundler" and "bundle install". My gemlist now looks like this:

Bundler can't satisfy your Gemfile's dependencies.
Install missing gems with `bundle install`.

The last three lines keep on repeating forever but with different numbers. So what is the problem this time?
Drush is a PHP app, not an Ruby one.
You need a PHP work environment (at first an PHP cli) to work with drush.

Is it a known bug? or am i doing something wrong?
For Ruby 2.0.0-p0, I also get similar warnings from gem check. However, I don't have issues at runtime with any of these gems. I suspect this might be a bug with Rubygems check command in 2.0.0.
I have similar errors. Passing options to compiler fix installation.
Before install readline and openssl with Homebrew.
RUBY_CONFIGURE_OPTS="--with-readline-dir=$(brew --prefix readline)
--with-openssl-dir=$(brew --prefix openssl)" rbenv install 2.0.0-p0

I am trying to install the gem melomel for testing in actionscript. When i require it in my gemfile and bundle update, i get an error saying that it cant find the gem tenderlove-frex and outputs this message:
Could not find gem 'tenderlove-frex (>= 0) ruby', which is required by gem 'spree (>= 0) ruby', in any of the sources.Bundler could not find compatible versions for gem "nokogiri":
In Gemfile:
spree (>= 0) ruby depends on
nokogiri (~> 1.5.0) ruby
spree (>= 0) ruby depends on
nokogiri (1.0.0)
When i remove melomel form my gemfile, bundle updates fine. I have looked all over online and it seems like every location where its been hosted has removed the gem.
Where can I get this gem? i am using ruby 1.9.3.
The frex gem is not hosted on the typical Gemcutter.
To get it, add GitHub to your gem sources:
gem sources -a http://gems.github.com
Then try installing the gem as usual:
gem install tenderlove-frex
In case it's helpful: tenderlove is the handle of Aaron Patterson, one of the top Ruby developers, and as far as I know he's replaced frex and likely has a better solution you can use. For example, can you update your Nokogiri gem to the current version, and also your Spree gem to the current version? This should remove the need for frex.
To see your versions:
$ gem list melomel
melomel (0.6.6)
$ gem list spree
spree (1.2.2)
spree_api (1.2.2)
spree_cmd (1.2.2)
spree_core (1.2.2)
spree_dash (1.2.2)
spree_promo (1.2.2)
spree_sample (1.2.2)
To update:
$ bundle update
To see dependency list for Nokogiri:
$ gem dependency nokogiri
