Failure to install or update any gem through Win CMD

[Alexis Cretton]

Hello,

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
encoutered.

Anybody here can help out?

Are you running the same version of Ruby on both setups, and which version is it
ruby -v
will tell you.

You may well have difficulties getting help with a Windows setup
however, as few Rails developers use Win.

The error you've described looks a lot like this one:

https://github.com/rubinius/rubinius/issues/2929#issuecomment-34701873

Can you run the script linked there and paste your output? 

Since this is (potentially) a networking issue, any information about your setup (system version, network config, any proxies in use, etc) would be useful.
