How does this error comes?

It looks like you have everything correctly configured, so my only guess given what you have provided is that the archive-zip gem isn't being included in your application. Make sure that any group or platform filter of which archive-zip may be a member in your Gemfile is loaded by your application.

As a quick hack, you may also write a short controller that simply dumps the content of the load path ($:) so that you can check to see if archive/zip.rb should be located.
