mina deploy throws error - bundle: command not found ! ERROR: Deploy failed

Question

Am trying to deploy rails app to digital ocean using mina gem. I did all the configuration and mina setup also is getting executed properly.

mina deploy throws error. Any help would be much appreciated.

Here is the mina deploy --trace

I Some how felt its something to do with the path to executable directory, hence did this.. gem environment - gives this.

Answer 1

Bundler has to be installed on your server machine (the one you trying to deploy to). The easiest way is to login into it by ssh and run gem install bundler once. It's listed as a common question in official mina FAQ

Answer 2

I have this issue as well, and workaround it by moving my launch tasks to a separate task. So you could do this by turning

task :deploy do
  deploy do
    comment "Deploying #{fetch(:application_name)} to #{fetch(:domain)}:#{fetch(:deploy_to)}"
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    on :launch do
      invoke :'puma:phased_restart'
    end
  end

end

to

task :deploy do
  deploy do
    comment "Deploying #{fetch(:application_name)} to #{fetch(:domain)}:#{fetch(:deploy_to)}"
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'
  end
end

task :launch do
  invoke :'puma:phased_restart'
end

And then execute it separately (which is admittedly suboptimal):

$ mina deploy
$ mina launch

I don't know the particulars of your task, but I configure mine like so:

task :launch => :remote_environment do
  in_path(fetch(:current_path)) do
    invoke :'my:task'
  end
end

I know this isn't a solution or explanation, but hopefully it helps.

Answer 3

For me the issue was with rbenv not being loaded.

If you're sure that ruby and bundler are correctly installed on the server as I was then the fix is to make sure the first thing your shell does it to load rbenv.

Open .bashrc

Make sure the following is called before

# If not running interactively, don't do anything

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
