I'm trying to install rails using 

$ sudo gem install rails

But I get this error:

ERROR:  While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
no such name (https://rubygems.org/quick/Marshal.4.8/activerecord-4.0.2.gemspec.rz

What am I doing wrong? do I have to use sudo apt-get install rails instead?

I have in my system

$ ruby -v
> 2.1.11
$ gem -v 
> ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]

I'm following these instructions

Solved

How did I solved it?

I followed this as Mitch advised me, but after sudo apt-get install ruby1.9.3 I got that ruby -v showed ruby 1.8.7

So I did this and then I continue with

sudo gem install rails

it worked.

  • Really? Could you show me an screenshoot of the message that you get when trying to answer your own post? Upload it into imgur.com and link it here – Lucio Dec 22 '13 at 23:04
  • @Lucio now I can. It's my first post here so yesterday my reputacion was 1(too slow). That's why I guess I couldn't. – Andres Dec 23 '13 at 00:57
