Failure to install or update any gem through Win CMD

Rails
1

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?

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

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.
