I've been trying to install and update different gems to work with Ruby on Rails, but keep getting the same error, apparently indicating I can't install or update any gem:
I generally type in something like:
gem update --system or gem install Rails --version 4.0.0 --no-ri --no-rdoc
And get the following:
ERROR: While executing gem ... (Errno::EINVAL)
Invalid Argument - socket(2) - udp
Note that I've proceeded to the same setup just a couple of days before on a different machine and had no problem.
I couldn't figure any place where this same Error was explained or encountered.
Anybody here can help out?
