Deleting a ruby version causes rehash to error due to ruby_profiles.yml being out of sync

[christophermanning]

I am using ruby-build and when I delete a ruby version, ruby_profiles.yml gets out of sync and will error when running rbenv rehash:

c@c:~/project$ rbenv rehash
/home/c/.rbenv/plugins/bundler/etc/rbenv.d/bundler/rehash.rb:343:in `ensure_capable_ruby': undefined method `ruby_version' for nil:NilClass (NoMethodError)
from /home/c/.rbenv/plugins/bundler/etc/rbenv.d/bundler/rehash.rb:342:in `select'
from /home/c/.rbenv/plugins/bundler/etc/rbenv.d/bundler/rehash.rb:342:in `ensure_capable_ruby'
from /home/c/.rbenv/plugins/bundler/etc/rbenv.d/bundler/rehash.rb:396

If you just compare against the mtime of the versions directory at RbenvBundler.build_ruby_profiles that should detect if a folder/ruby version has been added/deleted.

I'm having trouble reproducing your bug. From my understanding, the only way to get a NilClass problem is for the ruby_profile_map Hash to have a Ruby version key and a nil value. How does the plugin generate such a ruby_profiles.yml file in the first place? Would you mind sharing yours?

How does the fix look? I committed into a temporary branch, fix-issue-19.

Thanks for making those changes, but I've already deleted the broken ruby_profiles.yml file and I can't reproduce this issue starting from a fresh install. So, I can't say if this fixes the issue for sure or not.

If someone else has this issue and can reproduce it, then it might be worth merging that branch.
