is there supposed to be a ~/.rbenv/bin directory?

[salex]

I have a server (OS X server) running several small rails applications. I had initially set it using brew to install ruby (could not get rvm to install!). I made some changes to one of the apps and ran into all kinds of problems with I updated the brew ruby version. I decided to try rbenv and set it up on the server. Lots of problems with clashes with the brew version that I eventually figured out.

I then tried to deploy and discovered that my bundle update loaded capistrano 3.1 and nothing worked. I started the conversion processes and I got stuck on:

set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} #{fetch(:rbenv_path)}/bin/rbenv exec"

I have no bin directory on what brew installed for rbenv. I changed it to:

set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} /usr/local/bin/rbenv exec"

and got it to work, but maybe I'm missing something. I did get a basic deploy to work, but still have to get the rest of my 'railscast/recipes' to work, like writing plists for launchd etc.

If you use Homebrew, your rbenv_ruby path should be /usr/local/Cellar/rbenv/0.4.0

[kirs]

That means you don't need to change rbenv_prefix at all.

[salex]

Thank you. Knew it had to be simpler. Again, new to rbenv and did the Capistrano using the recipes screencasts, not really understanding Capistrano -- I'll work on that.

@salex, did you manage to get it working?

Is it as such:

set :rbenv_ruby, '/usr/local/Cellar/rbenv/0.4.0'

Don't think that is working on my side. Also do we need the .ruby-version file?

[kirs]

@mech rbenv_ruby should point to ruby version, not the directory with rbenv

[mech]

If I put the config as such

set :rbenv_type, :user
set :rbenv_ruby, '2.1.4'

I will get this error

bash: /Users/mech/.rbenv/bin/rbenv: No such file or directory

That's why it is puzzling how come it need to find such directory on a Mac OS X setup. I feel that it is like only for Linux. Obviously in a Mac using a typical install of rbenv with Homebrew, there is no such directory :(

Based on the settings listed in the Usage section of capistrano/rbenv, the following worked by changing the path to the actual rbenv executable (/usr/local/bin/rbenv).

set :rbenv_prefix, "RBENV_ROOT=#{fetch(:rbenv_path)} RBENV_VERSION=#{fetch(:rbenv_ruby)} /usr/local/bin/rbenv exec"

I had to set :rbenv_path, '/usr/local/opt/rbenv' in addition to @shawnpyle's solution to get rbenv to find the bundler executable.

@kirs, did you mean that this is already the default for rbenv_ruby and there's nothing to set?

If you use Homebrew, your rbenv_ruby path should be /usr/local/Cellar/rbenv/0.4.0

I'm wondering because you also said:

@mech rbenv_ruby should point to ruby version, not the directory with rbenv

---

Does this mean 'don't even set (rather than change) rbenv_prefix at all':

That means you don't need to change rbenv_prefix at all.

---

To avoid /Users/jason/.rbenv/bin/rbenv: No such file or directory, I had to:
ln -s /usr/local/Cellar/rbenv/1.1.1/bin ~/.rbenv/bin
Of course, this will break when rbenv is updated.

What's the proper way to set this up when installing with Homebrew? Thank you!

In my case I installed the Ubuntu rbenv package. This seems to place the binary elsewhere (outside of the .rbenv path). To fix this you need to configure it explicitly:

set :rbenv_prefix, '/usr/bin/rbenv exec'

Use which rbenv on your server to find the correct location.

You can see the logic around this here::

rbenv/lib/capistrano/tasks/rbenv.rake

Line 19 in 1fdb93a

rbenv_prefix = fetch(:rbenv_prefix, proc { "#{fetch(:rbenv_path)}/bin/rbenv exec" })

rbenv/lib/capistrano/tasks/rbenv.rake

Lines 35 to 45 in 1fdb93a

	set :rbenv_path, -> {
	rbenv_path = fetch(:rbenv_custom_path)
	rbenv_path ||= case fetch(:rbenv_type, :user)
	when :system
	'/usr/local/rbenv'
	when :fullstaq
	'/usr/lib/rbenv'
	else
	'$HOME/.rbenv'
	end
	}
