I have an Ubuntu server to deploy my Rails projects. In my Ubuntu server I had RVM.
Now I want to deploy new projects with Rails 5.1 and webpacker. To deploy this projects, I've installed NVM, npm and yarn in my Ubuntu server.
In my Rails 5.1 / Webpacker project I have following gems for capistrano deployment:
Gemfile
group :development do
gem 'capistrano-rails'
gem 'capistrano-rvm'
gem 'capistrano-passenger'
gem 'capistrano-nvm', require: false
gem 'capistrano-yarn'
end
In deploy.rb I've added some configurations for capistrano nvm and capistrano yarn.
deploy.rb
set :nvm_type, :user # or :system, depends on your nvm setup
set :nvm_node, 'v7.10.0'
set :nvm_map_bins, %w{node npm yarn}
set :yarn_target_path, -> { release_path.join('client') } #
set :yarn_flags, '--production --silent --no-progress' # default
set :yarn_roles, :all # default
set :yarn_env_variables, {}
Also I've added node_modules in linked_dirs.
deploy.rb
set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system node_modules client/node_modules}
The problem comes when I execute cap deploy in assets:precompile step. Next you have the error log.
terminal log

Thanks in advance!
The error tells you pretty much what's wrong. Neither Yarn or Node can be found on the server. Your installation might be incorrect.
Follow instructions to install both here:
https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
and here:
https://yarnpkg.com/lang/en/docs/install/#linux-tab
Then make sure you can call:
yarn
node
On the server. If not, you might need to add paths to executables into your PATH variable
