Any idea what's wrong ? I added /var/www/project/gems in the GEM_PATH yet require 'slim' won't load the gem, why so ? Is this a bug with rubygems ?
Same problem when i write require 'slim' in /var/www/project/index.rb and ruby index.rb.
I would heartily recommend using bundler, which will not only manage this but also version pinning and deployment on your behalf.
The relevant invocation would be; in Gemfile
source :rubygems
gem "slim"
And then
gem install bundler && bundle install && bundle exec irb
At which point require 'slim' will work.
Since you're installing slim at /var/www/project/gems/ you'll have to add it to the load path or require it by full path:
require '/var/www/project/gems/slim'
or add it to your load path:
$LOAD_PATH.unshift(File.dirname('/var/www/project/gems/'))

I've installed a gem from command line:
sudo gem install jalalidate
gem says it's installed:
$ gem list jalalidate
*** LOCAL GEMS ***
jalalidate (0.3.2)
And it can be loaded:
ruby -rubygems -e 'require "jalalidate"' # output is empty, (success?)
Though when I try to include this gem in a Rakefile, rake fails:
# Rakefile:
require "rubygems"
require "bundler/setup"
require "stringex"
require "jalalidate"
# Terminal:
$ rake new_post["title"]
rake aborted!
cannot load such file -- jalalidate
(See full trace by running task with --trace)
Note:
I'm using octopress blogging system, and I'm trying to convert dates generated by Time.now.strftime('%Y-%m-%d %H:%M') to Jalali calender system, (JalaliDate.new(Date.today).strftime('%Y-%m-%d')).
I'm not familiar with Ruby

Your Rakefile has require "bundler/setup" before you try to require jalalidate which means you are using Bundler and so you have a Gemfile, which is restricting the gems (and versions) available.
In order to use the gem in your project, add the line
gem "jalalidate"
to the Gemfile.
See this question about why using sudo with gem commands is mostly a bad idea.
I recommend trying to install the gem without sudo: gem install jalalidate
I really have some problems with gem. I'm trying to install racc for ruby so that it can compiler some *.y files. I'm working with my own laptop with Ubuntu.
The path of my ruby is
$ which ruby
/usr/bin/ruby
I'm a freshman of ruby. I have tried to install racc with sudo apt-get install racc. But it doesn't work. By the way, what's the difference between apt-get and gem?
$ sudo gem install racc

Any help is appreciated. I almost crazy for it.
I have already solved that. It turns out to be I need to install a full ruby with sudo apt-get install ruby-dev
I wrote a script todo.rb, whose first line is #!/usr/bin/env ruby. However, running this script gives the following error:

I'm using rvm under both Ubuntu and Mac OS X. From my Ubuntu box, this shebang line works fine. However, it sucks under OS X. So what's the reliable way to find out the usable ruby?
The problem is here:
λ ~/ which ruby
ruby: aliased to bundled_ruby
you need to check:
which bundled_ruby
and make sure it also has proper shebang:
#!/usr/bin/env ruby
finally removing the alias for ruby should solve the problem, you might want check my gem rubygems-bundler which is by default installed with RVM - it provides more "intelligent" means of detecting and using bundler.

Is there something I'm missing here? Do I need to configure it somehow?

Hey I was having this same issue. I am also the one that put the bounty up. I finally got passed this error. this is what i did.
As you correctly did, I installed the gem.
gem install win32console
then I went into my gemfile and also added this gem to the bottom.
Seems to work! How do I get my bounty back!!
According to example from here: https://github.com/luislavena/win32console you should:
require 'rubygems'
require 'win32console'
include Win32::Console::ANSI
include Term::ANSIColor
In the same README you can read that
Win32::Console has been deprecated in favor of an external tool named ANSICON:
http://blog.mmediasys.com/2010/11/24/we-all-love-colors/
https://github.com/adoxa/ansicon
ANSICON is universal tool and you use it in ruby with gem: https://github.com/flori/term-ansicolor
See this thread: http://www.ruby-forum.com/topic/133808
Hi everybody,
I figured out, what the problem was:
Just renamed the path in the gems dir:
win32console-1.0.8-x86-mswin32
to
win32console-1.0.8-i386-mswin32
then it works for me.

I've encountered similar problems on Ubuntu before, but they were easy to fix. I can't figure out what's wrong in this particular case, and Google didn't seem to know either. Any help would be greatly appreciated!
By the way... this is my first submission to stackoverflow. I hope this question is relevant. :)
Debian does not load RubyGems by default. You can solve this by adding require 'rubygems' to your code or better still, have RubyGems loaded each time Ruby is run. I also run #! and achieved this by editing my ~/.profile adding export RUBYOPT=rubygems and finally reloading my profile with . ~/.profile.
For more information on this matter see: http://docs.rubygems.org/read/chapter/3
Is nokogiri in any of the directories in GEM PATHS?
I've had problems before with installing rubygems from the Debian repos and then installing in manually. Debian puts all gems in /var/ somewhere in the distribution package.
