Issue #9156 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Feedback It's by a security reason. What's your platform? ---------------------------------------- Bug #9156: Not able to get tmp dir to work with Ruby 2.0.0 https://bugs.ruby-lang.org/issues/9156#change-43157 Author: saipas (Ben Larralde) Status: Feedback Priority: Normal Assignee: Category: Target version: ruby -v: ruby-2.0.0-p353 Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN I just migrated to Ruby 2.0.0 from 1.9.2 and I'm getting errors when trying to handle files because I can't get tmp directories to work. If you check this file and look at line 29 you'll see that a check on world_writable? has been added, but the file should not be world writable (prepended by !). So tmp dir are now restricted? What should I do to set up my machine? (I'm using Rails 4) Here's the error I get: ArgumentError: could not find a temporary directory When I try to hit Dir:tmpdir /home/ben/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/2.0.0/tmpdir.rb: in tmpdir raise ArgumentError, "could not find a temporary directory" if !tmp Thanks Ben -- http://bugs.ruby-lang.org/
