Ruby 2.0 RPM - Rails can't find psych

[Peter Deffendol]

Hi,

I rebuilt the ruby-2.0.0.0-6 packages on CentOS 6 (requiring a couple of slight
modifications to the spec file) and ran into some trouble:

[pete@centos railstest]$ ./script/rails c

/usr/share/ruby/yaml.rb:6:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
/usr/share/ruby/yaml.rb:7:in `require': cannot load such file -- psych (LoadError)
	from /usr/share/ruby/yaml.rb:7:in `<top (required)>'
<snip>

I have all of the relevant packages installed - rubygem-psych, libyaml (from EPEL).

If I run an irb session, it loads correctly:

[pete@centos ~]$ irb
irb(main):001:0> require 'yaml'
=> true

I'm not sure where to look.  The load path is identical in both situations (puts $:)

/usr/local/share/ruby/site_ruby
/usr/local/lib64/ruby/site_ruby
/usr/share/ruby/vendor_ruby
/usr/lib64/ruby/vendor_ruby
/usr/share/rubygems
/usr/share/ruby
/usr/lib64/ruby/


Can anyone confirm if this also occurs on the Fedora-built packages, and have any idea as
to why this is happening?

Thanks!

Pete

This seems to be Bundler issue IMO. You should add Psych into your Gemfile.

Vít.

Thanks Vit - I had that thought as well.  However, I get a slightly different message
after adding "gem 'psych'" to the Gemfile, running "bundle
install", and then trying the Rails console:

[pete@centos yamltest]$ ./script/rails c
/usr/share/ruby/yaml.rb:6:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
/usr/share/gems/gems/psych-2.0.0/lib/psych.rb:1:in `require': cannot load such file --
psych.so (LoadError)

You must use Fedora's Bundler. It is due to filesystem layout.

OK, I tried the patch in the Fedora bundler package.  That takes care of it.

Yes, that is another possibility :)
