Does it affect other Ruby builds, or just these two?

@jeremy No it affects only these two. I've successfully installed a 1.9, 2.0, 2.1 and 2.2 MRI on the same machine.

I got same error from another user: https://gist.github.com/kurotaky/726a442fc8812fb2e142

It's defects of ruby package.

what is version of your default ruby(which -a ruby)?

[olivierlacan]

@hsbt It's 2.0.0p645. It ships with OS X 10.11.

$ which -a ruby
/Users/olivierlacan/.rbenv/shims/ruby
/usr/bin/ruby
$ /usr/bin/ruby -v
ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]

Do you suggest upgrading the system version?

[hsbt]

Do you suggest upgrading the system version?

@olivierlacan No, system version is not related this issue. I can't reproduce this issue with OSX 10.11 and my enviroment.

Ruby core team(includes me) have to fix before 2.3.0 release. I addressed this issue to our tracker https://bugs.ruby-lang.org/issues/11807

[olivierlacan]

@hsbt Appreciate your help on this. I'll follow up and subscribe to the ruby-lang issue.

see #833 (comment)

[olivierlacan]

@hsbt I installed both preview1 and preview2 from 2.1.6p336. So this is unlikely to be the cause.

[olivierlacan]

@hsbt My bad, I just noticed I didn't set a global Ruby version. I'm sorry. We should probably file a radar bug report with Apple to let them know that they need to move off of ruby 2.0.0p645, no?

[hsbt]

It causes rbenv regression addressed rbenv/rbenv@dc23ef1 . so you need not report Apple :)

Please update your rbenv.

[olivierlacan]

@hsbt Oh okay, good to know. Thanks :-)

[olivierlacan]

This workaround suggested by @hsbt fixed my issue:

rbenv install 2.2.3
rbenv global 2.2.3

That said I'm going to leave this open until I can verify the regression fix from rbenv/rbenv@dc23ef1.

[olivierlacan]

Fix from rbenv/rbenv@dc23ef1 verified with rbenv global system set to ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15] which is the system default on OS 10.11.1.

Closing.

[hsbt]

Thank you for your feedback. I'm happy to fix this issue before Ruby 2.3.0 release.
