Using rubyzip error - no such file to load -- zip/zip

I know there is another thread on this subject but I still face this problem even after using all solutions. Is there any other way to generate zip files? Can i use Ubuntu system commands?

I did

 gem install rubyzip

I have

require 'rubygems'
require 'zip/zip'

in my controller

But i still get the same error - no such file to load -- zip/zip I tried with both ruby 1.8.7 and ruby 1.9.2 with rails 3.0.5 on Ubuntu

Could you please help me? Thanks.

Building on @eagor's answer, if you'd like to use rubyzip >= 1.0 but need backwards compatibility add this to your Gemfile:

gem 'zip-zip'

Saves updating legacy code.

When upgrading rubyzip to 1.0.0 change require 'zip/zip' to require 'zip'.

I fixed this problem by specifying gem version 0.9.9 in Gemfile:

gem 'rubyzip',  "~> 0.9.9"

Using rubyzip (1.0.0) caused an error. There's a note about this on rubyzip gihub:

Rubyzip interface changed!!! No need to do require "zip/zip" and Zip prefix in class names removed. If you have issues with any third-party gems what required rubyzip you can use next temporary fix:

# Place this line before your library or on the head of your Gemfile
gem 'rubyzip', '< 1.0.0'

In my case I was needed to change from 

Zip::File.open(...)

to

Zip::ZipFile.open(...)

of course I need to also add this to Gemfile:

gem 'rubyzip', :require => 'zip/zip'

Also make sure that your unzipping process uses:

Zip::ZipFile.open(self.data) do |zipfile|

not 

Zip::Zipfile.open(self.data) do |zipfile|

The capital F on ZipFile makes a difference.

After spending lot of time, I finally figured out the missing part. When using the rubyzip gem, I also had to require zip/zip.

Add this to your Gemfile

gem 'rubyzip', :require => 'zip/zip'

Just adding gem 'rubyzip did not work for me.

For anyone else who has problems with rubyzip and comes across this thread: remember that you can always shell out to an external command-line zip utility. There are a number of free command-line utilities which you can find through Google. Once you install your command-line zip program of choice and make sure it is on the system path, just use backticks to drive it from within Ruby. Of course, this won't work for web applications which are running on Heroku, etc.
