Bug 484376 – dev-ruby/rails-3.2.14 with dev-ruby/rdoc-4.0.1-r1 - Could not find gem 'rdoc (~> 3.4) ruby', which is required by gem 'rails (>= 0) ruby', in any of the sources.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michael Orlitzky 2013-09-09 19:22:14 UTC]

After fixing bug #483638, passenger will bomb with the following:

  Could not find gem 'rdoc (~> 3.4) ruby', which is required by gem 'rails (>= 0) ruby', in any of the sources.

So it looks like rails-3.2.x requires rdoc 3.x.

For a temporary fix:

  # emerge -C =dev-lang/ruby-2.0.0_p247-r1
  # emerge -1 =dev-ruby/rdoc-3.12.2

I've been trying to decouple my (custom) rails apps from bundler. This can prevent bug #483638, but I still get an error from passenger here about the incompatible rdoc:

  Could not find 'rdoc' (~> 3.4) - did find: [rdoc-4.0.1] (Gem::LoadError)

As far as I can tell rails 3.2.14 and 3.2.15 should already work with rdoc 4.x since we already rewrite the gemspec for this. If this still happens with rails 3.2.15 could you provide a more verbose error log for this? Perhaps some other package is actually triggering this.

Yep, fixed in 3.2.15, thanks.
