Problem installing Rails



I can’t seem to get gem to install rails on my machine :(. What I see
displayed is this: (after running

“gem install rails --include-dependencies”

Upgrading installed gems…
Updating Gem source index for:
ERROR: While executing gem … (Errno::EINVAL)
Invalid argument

I’ve tried googling for answers and tried basically everything I could,
including disabling my firewall

and switching off my anti-virus, attaching “–http-proxy” to the install
command, and resetting my

winsock (via “netsh winsock reset”). Nothing seems to work :(. I can’t
even run “gem update”…

I’d really appreciate any help on this matter.

Thanks in advance!
