Ubuntu – Ruby command not recognized after installing it with rvm

rubyrvmsoftware installation

I followed this tutorial to install ruby with rvm: https://www.digitalocean.com/community/tutorials/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm

The problem is that everytime that I log in, the ruby installation is not recognized, for example if I try executing a ruby script with the "ruby" command this is what I get:

enter image description here

To make it be recognized I have to run this command:

source ~/.rvm/scripts/rvm

But every time I login I have to do it again.

You can install Ruby by typing:

sudo apt-get install ruby-full

See the Doc.

Ubuntu – Sudo: ruby: command not found after ssh

The error you are getting indicates that ruby is not in the sudo $PATH. TO get around this, you either need to export your environment correctly:

sudo -E ruby

Or, just use the full path. Run type ruby as your regular user, and use that with sudo. For example:

$ type ruby
ruby is /usr/bin/ruby
$ sudo /usr/bin/ruby
