I get this error while running bundle install in a rails app,
I thought the latest version is 0.2.0...could anybody help me out on this?
bundle insta
As dreamnid said, "Look like they yank the 0.3.0 build a few hours ago to troubleshoot a build issue".
Try to run gem uninstall thread_safe (to remove yanked version) and later bundle update to install the correct versions.
gem uninstall thread_safe
bundle update
