I just finished lewagon's setup for mac with OSX El Capitan. So I get the lastest version of all my gems and programs. Of course, I have apps running under ruby 2.2.0 and I did not specify the version of gems in gemfile.
puma causes problems so I can't run
bundle install. In general, how can I know with gem version is compatible with ruby 2.2.0?
Solved installing the latest version of puma :tiger:
