Error when installing on Ruby 2.5.0 with rbenv

[simonszu]

Hi,
i manage my rubies with rbenv. While it is not the best approach for executables like gas, and i have still to find a way to streamline this, i just want you to know that i get an error when installing gas with an rbenv'd 2.5.0:

$ gem install gas                                                                          [10:57:04]
Fetching: gas-1.0.3.gem (100%)
Successfully installed gas-1.0.3
ERROR:  While executing gem ... (TypeError)
