Deploy Rails 5.1 / Webpacker app with Capistrano


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

Solution

  • 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
