Capifony database functions fail with `require': cannot load such file -- FileUtils (LoadError)

Question

When I call any of the Capifony database functions, cap database:move:to_remote for example, I get the following ruby error:

jeremykendall@isr-thinkpad-420s:~/dev/sites/app$ cap develop database:move:to_remote
    triggering load callbacks
* executing `develop'
    triggering start callbacks for `database:move:to_remote'
* executing `multistage:ensure'
* executing `database:move:to_remote'
* executing `database:dump:local'

What I've Tried

• gem install fileutils
• sudo aptitude install libfileutils-ocaml-dev (grasping at FileUtils straws)
• gem update --system
• gem update

Answer 1

Looks like it's a bug in capifony 2.1.5. Try grepping for require "FileUtils" and replacing with require "fileutils". That or maybe wait for the patch?

Answer 2

You'll find that require 'FileUtils' will generally work on Mac OS X, however it is supposed to be lowercase fileutils. The problem is that most use Mac OS X with case insensitive filesystems and therefore when you deploy or move over to linux or other filesystems such as ZFS with case sensitivity turned on, it will fail.
