Capistrano 3 无用的错误信息

Question

我试图通过 capistrano 任务弄清楚运行这个命令有什么问题。如果我运行直接在服务器上运行没问题:

desc 'Run npm install on remote server'
  task :npm_install do
    on roles(:app) do
      puts '**** NPM INSTALL ****'
      execute "cd /var/www/#{fetch(:application)}/current/hapi && NODE_ENV=#{fetch(:env)} npm install"
    end
  end

没有多大帮助的错误

$ cap prod deploy:npm_install
**** NPM INSTALL ****
INFO [23ed2aa2] Running /usr/bin/env cd /var/www/myapp/current/hapi && NODE_ENV=prod npm install as myuser@123.456.789.101

有什么方法可以通过 capistrano 打开有用的错误消息或远程任务的东西吗运行？
