Warning: require_gem is obsolete. Use gem instead


#1

Hello Friends,
This is a very common warning that everyone gets. I upgarded my gem
and rails version to gem 0.9.2 and rails1.2.3
After i changed the version i got the warning “warning: require_gem is
obsolete. Use gem instead”. so i changed all the require_gem to gem.
but after i changed it i got an error

./nxw-persistency-0.2/photo.rb:22: uninitialized constant
Crystallizer::ActiveRecord (NameError)
from C:/Program Files/ruby/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in gem_original_require' from C:/Program Files/ruby/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:inrequire’

my code where i am getting an error

module Crystallizer

require ‘rubygems’
gem ‘activerecord’

class Photo < ActiveRecord::Base(ERROR IS ON THIS LINE)

Any kind of help will be appreciated
Thank you

my code where i am getting an error

module Crystallizer

require ‘rubygems’
gem ‘activerecord’

What you want is just

require ‘activerecord’

gem is only needed if you’re looking to specify a specific version of
the gem.

when doing just require on my windows box it fails though and says it
has no idea what your talking about.

thoughts?

What is the specific error (as opposed to ‘no idea what i’m talking
about’)

That could help a bit more.

simple fix is to (useing rails 1.2.3)
generate a new directory tree and copy the new dir tree onto the old one
which should over write your base files with the new versions without
deleting your controllers/models/etc. then go into the enviroments file
and change the rails version number from 1.1.6(or what ever) to 1.2.3
then you should be good to go.

WARNING: back up your files first (your using svn right?)

hope this helps

I had the same problem. It was solved by adding an underscore:

require “rubygems”
require “active_record”
