当通过 capistrano 任务运行时，我试图弄清楚这个命令有什么问题。如果我直接在服务器上运行它运行良好：

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

cap aborted!

有没有办法为通过 capistrano 运行的远程任务打开有用的错误消息或某些东西？
