【问题讨论】：

执行'yarn run webpack'

标签： ruby-on-rails node.js npm webpack capistrano3

【解决方案1】：

你需要把这个添加到config/deploy.rb的底部：

before "deploy:assets:precompile", "deploy:yarn_install"
namespace :deploy do
  desc "Run rake yarn install"
  task :yarn_install do
    on roles(:web) do
      within release_path do
        execute("cd #{release_path} && yarn install --silent --no-progress --no-audit --no-optional")
      end
    end
  end
end

从https://github.com/rails/webpacker/blob/master/docs/deployment.md获得此代码

【解决方案2】：

您需要在 assets:precompile 之前运行任务 yarn install。
