Chef Recipe - 在 Ubuntu 上安装 DropBox 的交互式响应答案

【问题描述】：

我是 Chef 的新手，正在尝试学习如何通过 CLI 提供安装脚本的答案。我运气不好，希望能得到一些帮助吗？

  bash 'DropboxInstall' do 
  user 'root'
  cwd  '/opt/dropbox'
  code <<-EOH
       dropbox start -i
       expect "Starting Dropbox...\rDropbox is the easiest way to share and store your files online. Want to learn more? Head to https://www.dropbox.com/\rIn order to use Dropbox, you must download the proprietary daemon. [y/n]"
       send "y\r"
       dropbox autostart y
  EOH
end

我得到的错误是：

Chef 脚本正在完成安装，但是当它尝试从 CLI 执行“expect”时它会死机：

              Dropbox is the easiest way to share and store your files online. Want to learn more? Head to https://www.dropbox.com/

              In order to use Dropbox, you must download the proprietary daemon. [y/n] Traceback (most recent call last):

    - execute "bash"  "/tmp/chef-script20180423-29717-15l42km"

我毫不怀疑是我自己，但我已经阅读了一些内容，但不知道如何最好地解决这个问题。看起来当它尝试执行 bash 脚本时出现问题，但我尝试“cat /tmp/chef-script20180423-29717-15l42km”它不存在，所以我不知道如何解决这个问题。

提前致谢！

【问题讨论】：

你在显示实际失败之前切断了错误信息。
您好，感谢您的回复，我更新了整个调试块。任何想法都会非常感激。
另外，“为了使用 Dropbox，您必须下载专有的守护程序。”提示在大约 30 秒后出现是否重要？谢谢！
您似乎在尝试混合 shell 命令和期望命令？您所拥有的是一个 bash 脚本，因此它按顺序运行命令，而不是在 TTY 中。
您好 coderanger，谢谢！我最终作弊了一点，使用了expect和TCL。根据我所阅读的内容，它并不是最好的或推荐的方式，但 Dropbox 安装程序没有答案文件或无人值守的安装选项：-/ 谢谢队友，我很感激！如果这对其他人有帮助，请随意使用：

      mode '0755'
      owner 'root'
      group 'root'
      content 'puts "Running Dropbox Installer..."

               spawn dropbox start -i
               expect {

                      }
               exec sleep 360
                       puts "Dropbox installer completed"'
    end

    bash 'DropboxInstall' do
      user 'root'
      cwd  '/tmp'
      code <<-EOF
      /usr/bin/expect -d dropbox.sh
      EOF
