RVM is not a function

[harryworld]

I have setup the mina to a new server on 1and1.fr Ubuntu 14.04 dedicated server, with rvm 1.26.4 and ruby 2.1.5, if I logged in as ubuntu user, I can run rvm successfully, but if I use mina setup, it tells me the following error message on not using interactive shell.

Is there anyway to mina using login shell by default? Or switch to login shell after logging in?

require 'mina/rvm'
set :user, 'ubuntu'

task :environment do
  invoke :'rvm:use[ruby-2.1.5]'
end

You need to change your terminal emulator preferences to allow login shell.
       Sometimes it is required to use `/bin/bash --login` as the command.
       Please visit https://rvm.io/integration/gnome-terminal/ for an example.

+1 I've been fidgetting for the last 2 hours trying to get it to work.

+1, getting this error while trying to set up a new DigitalOcean droplet with Ubuntu.

RVM is not a function, selecting rubies with 'rvm use ...' will not work.

@harryworld @mrozbarry did either of you get this working, or did you abandon mina?

[mhuggins]

I figured it out! I had to change this line in my deploy.rb file from:

set :rvm_path, '/usr/local/rvm/bin/rvm'

to this:

set :rvm_path, '/usr/local/rvm/scripts/rvm'

The reason is that for a non-login, rvm must be sourced to run as a function instead of trying to run it as a binary as explained here. I was originally trying to add this to my server's user's .bashrc with no luck, not realizing that the mina deploy script was also calling source with the value of rvm_path, which ultimately overwrote that setting.

Note that you might need to set rvm path to ~/.rvm/scripts/rvm if not using a system-wide installation.

Thank @mhuggins for figuring this out!

@mhuggins I keep on using mina, it works without configuring that properly.
I tried your way, and it works now. Thanks.

I saw that already and it still doesn't work for me. I can use rvm when I log in manually but mina can't do it.

[adiakritos]

Figured out the issue.

When logged in manually I'm able to run rvm from this path:

'/usr/local/rvm/scripts/rvm'

So I thought that this is what mina should use. I kept reading paths in the answers provided that look like this: ~/.rvm/scritpts/rvm leading me to think they are not my path..

I turns out that I too have a folder called /scripts and an exe rvm in there. So my path is this:

/usr/local/rvm/scripts/rvm

This seemed to fix that issue. I have a different one now though :(

[flowerett]

That's because you're installed the rvm globally or for multi-user
But Single-User Install seems more general, so I don't think that we have an issue here.
more info: https://rvm.io/rvm/install#installation
And it's up to you to choose a path that you more comfortable with, just set your rvm_path like this:

set :rvm_path, '/usr/local/rvm/scripts/rvm'

as @mhuggins mentioned above.

In my case fix was change to set :rvm_use_path, '/home/deploy/.rvm/scripts/rvm' from set :rvm_use_path, '/home/deploy/.rvm/bin/rvm'
