When I try to require the tagfile/tagfile which is part of rtaglib I get a LoadError:
$ ruby main.rb
/usr/share/rubygems/rubygems/custom_require.rb:36:in `require': cannot load such file -- tagfile/tagfile (LoadError)
from /usr/share/rubygems/rubygems/custom_require.rb:36:in `require'
from main.rb:4:in `<main>'
I installed rtaglib with
$ gem install rtaglib
Here is the top part of my main.rb:
require 'date'
require 'find'
require 'tagfile/tagfile'
None of the suggestions here (Problem with Ruby + rtaglib gem) work. taglib is installed (1.7.2)
Trying it with other gems, like sinatra, works perfectly. Does anyone know the reason I cannot load rtaglib?
Can't you just require 'tagfile'? I just tried it and it worked fine.

When I type
gem list
I see the following
...
activerecord (3.2.17, 3.2.13)
...
But when I type this
cat >> does_ar_exist.rb
require 'activerecord'
ActiveRecord
ruby does_ar_exist.rb
I get the following error:
/Users/xxxxxx/.rvm/rubies/ruby-1.9.3-p448/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:51:in `require': cannot load such file -- activerecord (LoadError)
from /Users/xxxxxx/.rvm/rubies/ruby-1.9.3-p448/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:51:in `require'
Does anyone know why this is happening?
You have to do:
require 'active_record'
instead of require 'activerecord', since the file you want to load is active_record.rb.
I am sure this is a simple issue but since I have looked so long I cannot see it. So I am running ruby 1.9.3 with Sinatra, sqlite3, datamapper, dm-sqlite-adapter. When I try to run Sinatra, I get this:
/Users/XXX/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- datamapper (LoadError)
from /Users/XXX/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from app.rb:2:in `<main>'
Here are the first two lines:
require 'sinatra'
require 'datamapper'
The gem is installed. (datamapper (1.2.0))
You need to require data_mapper, not datamapper (note the underscore):
require 'data_mapper'
See the DataMapper getting started page.
I'm scripting with Ruby 1.9.2dev in Backtrack 5 but I'm having some problems when try to parse html entities with the library "htmlentities".
I cannot load the library although I have installed it with gem.
I'll show you the problems I'm having in the console:
root#bt:~# gem list -d htmlentities
*** LOCAL GEMS ***
htmlentities (4.3.1)
Author: Paul Battley
Homepage: https://github.com/threedaymonk/htmlentities
Installed at: /var/lib/gems/1.9.2
A module for encoding and decoding (X)HTML entities.
root#bt:~# irb irb(main):001:0> require 'htmlentities' LoadError: no such file to load -- htmlentities
from (irb):1:in `require'
from (irb):1
from /usr/bin/irb:12:in `<main>'
This is the same problem I'm having with nokogiri. I installed the library with
gem install htmlentities
Do you have any idea why I'm having this problem?
Thank you.
EDITED:
I tried also with require 'rubygems' previously to any other require, but happens the same:
I tried require 'rubygems' but is happening the same:
irb(main):001:0> require 'rubygems'
=> false
irb(main):002:0> require 'htmlentities'
LoadError: no such file to load -- htmlentities
from (irb):2:in `require'
from (irb):2
from /usr/bin/irb:12:in `<main>'
Try to require 'rubygems' before the rest of your gems requirements.
rubygems is actually redefining the Kernel#require method to look for gems on your gempath. Whitout it ruby will just look for local/on path files.
It took me a lot but now I know how to fix it. It's about GEM_PATH.
# echo "export GEM_PATH=/var/lib/gems/1.9.2/" >> ~/.bashrc
# source ~/.bashrc
Now if I run irb:
# irb
irb(main):003:0> require 'htmlentities'
=> true
irb(main):004:0>
WOOT!

I'm using Ruby 1.8.7. Also, this worked before (on the same computer).
The require statements all do work when I try things from interactive ruby.So they all are installed. But I need the command line.

Edit: Here are the contents of Hello.rb
puts "hello"
require 'rubygems'
require 'bundler/setup'
require 'date'
require 'watir'
require 'optparse'
And some new error:

Somehow, ruby bundle install doesn't work very well:
C:\Users\wipe\Quora-Personal-Analytics>ruby bundle install
ruby: No such file or directory -- bundle (LoadError)
It looks like you don't have bundler installed. Try running gem install bundler, and then rerun ruby hello.rb.
Also, the two last commands you're typing won't work. ruby require 'date' is going to try to run the file "require" and pass it the argument 'date', not execute require 'date'. To just execute one line of ruby, use the -e flag, like this:
ruby -e "require 'date'"
Your stacktrace says
`gem_original
_require': no such file to load -- bundler/setup (LoadError)
Did you make sure bundler is actually installed? If not, try
gem install bundler
and retry.
Edit:
With the new errors you receive, simply try running
`bundle install`
then try again.
ruby1.9.1-full
rubygems1.9.1
installed, these are the only versions i have installed.
I am not able to require any gems with the following syntax:
require 'rubygems'
require 'gem_name'
I get this error:
LoadError: no such file to load -- active_record
from (irb):2:in `require'
from (irb):2
from /usr/bin/irb:12:in `<main>'
I have to add this line to the syntax in order for it to work:
require 'rubygems'
gem 'gem_name' <---
require 'gem_name'
But with gems like active_record and sqlite3 i get this error:
Gem::LoadError: Could not find RubyGem sqlite3 (>= 0)
from /usr/local/lib/site_ruby/1.9.1/rubygems.rb:779:in `report_activate_error'
from /usr/local/lib/site_ruby/1.9.1/rubygems.rb:214:in `activate'
from /usr/local/lib/site_ruby/1.9.1/rubygems.rb:1082:in `gem'
from (irb):3
from /usr/bin/irb:12:in `<main>'
I have been searching and posting but i am still unable to find a solution for this, in a previous installation i had of ubuntu same version as now, i was able to require the gems normally, i'm not quite sure what could have changed.
I hope some one can help me on this one as this has me stuck.
Thanks in advance.
Jaime.
The proper gem name is sqlite3-ruby, not sqlite. Perhaps try gem'ing this instead?
could try it without gem prelude: https://github.com/rdp/ruby_tutorials_core/wiki/ruby-talk-faq#gem_loading_fails_191
