I installed Ruby and RubyGems on Ubuntu 10.04. Ruby is version 1.8.7. Gems is version 1.3.7. When I try sudo gem install rails, nothing happens. It just hangs forever. What am I missing? Thanks!

It'll take quite some time to install rails - there are lot of dependencies and these need to be downloaded - if you have a slow connection, just wait for a bit.

Thanks! I guess I was expecting an immediate response of some kind like with apt-get. – bsamek Sep 18 '10 at 23:48
I was on the same boat as you - thought it had given up but it was processing in the background. – Sathya Sep 18 '10 at 23:54
I have a lightning fast connection on a VPS server and this is still happening – boulder_ruby Sep 24 '15 at 19:43

Try adding -V (upper case) to the end of the install command, if forces the command to be verbose, so you can see things going on. Eg:

sudo gem install rails -V

Another thing to consider... open Task Manager (or equivalent - I'm using Xubuntu) and view process by CPU usage. That's the only indication I had that gem was actually doing anything until it eventually finished. – nathanchere Aug 4 '11 at 5:57
It was using so little CPU that I still didn't think it was doing anything. I tried -v but that didn't work - had to be uppercase! – cwd Feb 11 '13 at 15:37
seriously thank you, thought my gems was broken – Jessie Frazelle Aug 6 '13 at 21:39
That's what I am looking for! – Frank Fang Mar 30 '14 at 4:36
-V is the trick! Thank you! – ssoto Oct 26 '14 at 9:08
  1. try to add -V (upper-case) in the parameter, to show more detail of what is downloading
  2. if it still very slow or pending somewhere, it normally indicates a low internet connection to the site(showing in the output window). you can try to update the source of the gem using, by

    gem source -r

    gem source -a "your new source site"

in my country, after I switch to, it only takes 1min to complete the installation.

First option is better than just waiting for an empty line to show something – Ali Almoullim Apr 12 '15 at 19:45
