rbenv: version `2.2.3' is not installed (set by RBENV_VERSION environment variable)

Question

When I run a deploy script, I'm having errors:

[cb123fad]  rbenv: version `2.2.3' is not installed (set by RBENV_VERSION environment variable)

Capfile has set :rbenv_ruby, '2.2.3'

Server and locally I have installed ruby 2.2.3p173

Changing the value from 2.2.3 to 2.2.3p173 for set :rbenv_ruby didn't work.

I solved the same problem setting :rbenv_path. Yours should be:
set :rbenv_path, '/home/your/.rbenv/'

This must be inside of deploy.rb.

Hi! Unfortunately just adding set :rbenv_path in the Capfile didn't work for me. Thanks for your time. – Coadjutrix

This should be in deploy.rb, not Capfile. – Hooten

This fails for me set :rbenv_path, '~/.rbenv' in deploy.rb. The path is correct because if I alter it, cap immediately hits an error... This is something introduced recently; previous deploys were working. I really don't get it – Index

Thanx! You made my day. I was struggling with this problem for an hour :) However, strange, cause ruby -v showed correct version in my case, and bundle update etc. worked also OK. So this seems exclusively related to deployment with Capistrano. – Garlen

Like @jerome mentioned, you could abbreviate the path to a generic one: $HOME/.rbenv. This did work for me. – Hankow

https://github.com/capistrano/sshkit/issues/303 and https://github.com/capistrano/rbenv/pull/59

NOTES

set :rbenv_path, '/home/your/.rbenv/' # works
set :rbenv_path, '~your/.rbenv/' # doesn't work

This issue is created due to a change in sshkit.

Answer 3

The above answere did not work for me. gem update --system, then bundle install would lead to a fatal: No live threads left. Deadlock? error.

bundle exec cap development deploy

completes the deployment if gem 'sshkit', '~> 1.7.1' is spedified.

However, what may occur is that sshkitgem might get updated to 1.8.0or greater. In that case, assuming a standard Ubuntu server set-up, in deploy.rb

set :rbenv_path, '$HOME/.rbenv'

will allow deployments to complete.
