Question

I’m a relatively new linux and rails dev and I’m attempting the following setup:
Debian 6 / Rails 3.1.3 / Ruby 1.9.3

FYI:

1. My system is currently configured with Ruby 1.8.7…which is still installed and running
2. I have rails websites up and running on a Linode vhost apache2 setup

Following instructions here > https://rvm.io/rvm/install/ I did the following:

1. List item
2. I installed RVM
3. I reloaded my shell environment (btw I think Debian is $ source /etc/profile)
4. I installed Ruby 1.9.3
5. Run RVM use 1.9.3 –default
6. Added…echo ‘[[ -s “$HOME/.rvm/scripts/rvm” ]] && . “$HOME/.rvm/scripts/rvm” # Load RVM function’ >> ~/.bashrc…to my bash script (I also tried .profile)
7. Installed rails, gems etc

All seems well. When I run $ Ruby -v and it reads correctly. When I run gem list, all is good there too. When I run RVM list, it shows my versions and lists 1.9.3 as my default.

Issues:

1. List item
2. When I log out and log back in…if I run $ Ruby -v it shows version 1.8.7, not 1.9.3. So as far as my terminal goes, it’s not automatically using my default version.
3. My rails app still uses the old gem path.

Questions:

1. What am I missing here? Every tutorial I look at never goes past these steps. Am I missing something basic?
2. How do i make my rails app use the ruby version controlled by RVM
3. How do I make Debian recognize my bash function automatically?
4. Can anybody give me or point me to a more in depth explanation on how this all fits together?

Answer 1

As you are using Debian my guess is you use gnome-terminal, it is known to not have enabled login shell by default: https://rvm.io/integration/gnome-terminal/

More details on what shell login is:

• https://rvm.io/support/faq/#shell_login

the document describes current state of shell login, this was not always like this and it was confused and misused / misunderstood for long time (and still is in few tools and by few developers)
