Question

here is my deployment.rb file.
# config valid only for current version of Capistrano
lock '3.4.0'

set :use_sudo, false
set :rails_env, "production"

end
end
end
after "deploy", "deploy:restart"
after "deploy", "deploy:cleanup"
Now I did bundle exec cap production deploy. And after huge log I got the below error.
DEBUG [cced60a1] bash: bundle: command not found
(Backtrace restricted to imported tasks)

Answer 1

Looks like the bundler gem is not installed on your server. It should be installed and the bundle executable should be available in $PATH.
Try executing the bundle --version directly on the server to ascertain that bundler is actually missing.
If that is case, install the bundler gem and you should be good to go. Or to actually keep things automated you can define a capistrano task to check if the bundle executable is available or not and install the bundler gem if it is not available. You can execute this task before the bundler:install task.
UPDATE : If you are using some ruby manager like rvm or chruby or anything like that, the bundle executable might not be available to your Capistrano deploy task. In that case you have to make sure your deploy task gets a login shell so that all those shell scripts are executed.

Here is what I have now which resolved the issue. I got help from Rustam A. Gasanov to make it working. Thanks a lot!!
