rvm.rake:9: undefined method `include?' for nil:NilClass

[MiguelPF]

This line is causing me trouble: if fetch(:rvm_map_bins).include?(key.to_s)

Is it possible that this code should check the existence of rvm_map_bins before calling include?

[leehambley]

This like should always exist, unless you are loading things in a strange order, as far as I know?

[MiguelPF]

I think I am using the standard order: require 'capistrano/setup'

require 'capistrano/deploy' require 'capistrano/rvm' require 'capistrano/bundler'

I hack it with set :rvm_map_bins, []

[leehambley]

I didn't write the rvm integration, it was contributed by a 3rd party, so I hope they pick this issue up and can comment on whether this is expected.

[Kriechi]

the rvm_map_bins should be set to the correct value in the load:defaults task, which is executed prior every deploy-task. Please try and run cap production deploy -t and check which tasks are executed in which order. It should look somethink like this:

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke deploy (first_time)
** Execute deploy
** Invoke deploy:starting (first_time)
** Invoke deploy:ensure_stage (first_time)
** Execute deploy:ensure_stage
** Invoke deploy:set_shared_assets (first_time)
** Execute deploy:set_shared_assets
** Execute deploy:starting
** Invoke deploy:check (first_time)
** Execute deploy:check
** Invoke git:check (first_time)
** Invoke git:wrapper (first_time)
** Execute git:wrapper

[MiguelPF]

yes here it's my output: * Invoke production (first_time) * Execute production * Invoke deploy (first_time) * Execute deploy * Invoke deploy:starting (first_time) * Invoke deploy:ensure_stage (first_time) * Execute deploy:ensure_stage * Execute deploy:starting * Invoke deploy:check (first_time) * Execute deploy:check * Invoke git:check (first_time) * Invoke git:wrapper (first_time) \ Execute git:wrapper

I guess this bug should be in capistrano page then, right? Thank you

[Kriechi]

I think so, yes. It seems that the load:default task is not executed in your setup. Also I've noticed that the dry-run option for capistranor produced an error - also a bug not releated to this rvm plugin.

Just to be sure: you did specify the git-repository in your gemfile? Because the current gem version on rubygems is pretty old and has barley nothing to do with the current one right here.

[MiguelPF]

Yes, thank you, that was exactly my problem, I had the github version of capistrano/rvm but the rubygems version of capistrano, after changing the capistrano version to github repo v3 all went well

[contentfree]

I'm getting this same issue.

Relevant parts of Gemfile:

group :development do
  gem 'capistrano', github: 'capistrano/capistrano'
  gem 'capistrano-rails'
  gem 'capistrano-bundler'
  gem 'capistrano-rvm', github: 'capistrano/rvm'
end

Top of cap config.rb:

require 'capistrano/bundler'
require 'capistrano/rvm'       # Tried this above bundler too to no effect
require 'capistrano/rails'

Generates this error:

$ cap production rvm:check -t
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke rvm:check (first_time)
** Invoke rvm:hook (first_time)
** Execute rvm:hook
** Invoke rvm:init (first_time)
** Execute rvm:init

Tasks: TOP => rvm:init

load:defaults appears to be running, but it appears rvm_map_bins is still missing...

[contentfree]

I had to manually add the following to my config.rb (which is strange because I can plainly see where rvm.rake sets them in the load:defaults task):

set :rvm_map_bins, %w{bundle gem rake ruby}
set :rvm_type, :auto

[contentfree]

Maybe there's a problem with load:defaults? (Seems impossible, but I believe I'm seeing problems loading defaults from capistrano/bundler too)

[kirs]

It may be somehow connected with https://github.com/capistrano/capistrano/issues/640 @seenmyfate any ideas?

[contentfree]

Well, mine might be a case of the Idiots or it might be an important distinction to make:

To get things to work, I had to require 'capistrano/bundler' etc in Capfile and not config/deploy.rb

I believe this is related to capistrano/capistrano#640 in some way though it might just be a trade-off. load:defaults is invoked before config/deploy.rb is loaded so requireing bundler and rvm there means their load:defaults tasks never run.
