Ruby Question

Other user doesn't see Ruby installation

I have installed Ruby on my Ubuntu 14.04 server under the root account with rbenv.

root@droplet:~# ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [i686-linux]

But if I log in under another user I get this message after the same command:

The program 'ruby' can be found in the following packages:
* ruby
* ruby1.8

Why doesn't another user ee ruby installation? And how can I fix it?

I'm a complete newbie to it and I may have missed something important. So tell me if you want me to provide any other info on this matter.


To install Ruby with rbenv so that all users on a machine can use it, you need to

  • install rbenv in a public place, e.g. /usr/local/rbenv
  • set up rbenv for each user in a shell startup file, e.g. /etc/profile:

    export RBENV_ROOT=/usr/local/rbenv
    export PATH="$RBENV_ROOT/bin:$PATH"
    eval "$(rbenv init -)"

A blog post by Blake Williams gives details.
