knife cook should (?) force omnibus ruby if available

[aaronjensen]

Right now if sudo has acces to rvm it will use the rvm default ruby rather than the omnibus ruby. Any ideas how to work aroudn this?

[matschaffer]

That could be tricky since rvm also mucks with the path. Perhaps we could manipulate the path on a which call to get the full path to omnibus then call that directly?

[matschaffer]

If you have a set of recipes or AMI that reproduce the situation, definitely post it btw. I don't typically use rvm in production.

This issue on the chef-rvm repo may help: sous-chefs/rvm#125.

[matschaffer]

Thinking about this a bit more. If you run 'which chef-solo' what do you get? Do you have a copy of the chef gem under rvm as well? I would expect that the omnibus copy of chef-solo has a hardcoded path to the embedded ruby.

[hrp]

which chef-solo => /usr/bin/chef-solo

If I cook a second time I get this error:

/opt/chef/embedded/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find chef (>= 0) amongst [bundler-1.2.3, rake-10.0.3, rubygems-bundler-1.1.0, rvm-1.11.3.5] (Gem::LoadError)

Hey all, I've merged sous-chefs/rvm#125 into master.

@hrp It looks to me like RVM might be loaded (login shell perhaps?) and it's trying to use your default RVM Ruby's RubyGems. When I get this logged into a box I can usually clear it with an rvm system (it'll unset some of the RUBY_* and GEM_* envvars).

[matschaffer]

@hrp if @fnichol's recommendation works should we close this issue?

[hrp]

@matschaffer Sure, go ahead and close this. I haven't seen this problem lately (I've been using a fork of chef-rvm with the above commit included) so it may be solved. If I notice it again, I'll try @fnichol's solution. If that doesn't work out, I can reopen or make a new issue.

[matschaffer]

Thanks @hrp!

FWIW I had the same issue and "rvm system" resolved it for me.
