I got error message when installing ruby 2.3.1 using rbenv. My environment is below.
The log message is below.
$ rbenv install 2.3.1

If you get the same error, would you please tell me how to solve this error?
Thank you for your help.
Accepted answer is not a good answer - the install process should not require root privileges, and may lead to problems installing gems that require C extensions in the future (nokogiri is a good example).
It's a documented bug in the ruby-build package: https://github.com/rbenv/ruby-build/issues/992, the workaround is to navigate into the working directory and run make install yourself - which should run if you have XCode command line tools installed and updated.
