一切正常，直到第 32 行我试图找到哪些文件和目录需要上传到备份服务器。你能帮我把文件从 local_path 同步到 remote_path 吗？谢谢您的帮助！

当我运行它时，我得到：

box.ru:32:in `block (2 levels) in <main>': uninitialized constant Find (NameError)

def sanitize_string(string_name)
string_name.gsub(/[^\w\.\-]/,"_")
end


puts "box username:"
user0 = gets.chomp
user = sanitize_string(user0)

pass0 = ask("Enter password for #{user}: ") { |q| q.echo = false }
pass = sanitize_string(pass0)

puts 'connecting to box...'
Net::SSH.start( host, user, :password => pass ) do|ssh|
result = ssh.exec!("cd #{remote_path} && ls")
 puts result
   ssh.sftp.connect do |sftp| 
 puts 'Checking for files which need updating'
 Find.find(local_path) do |file|
     next if File.stat(file).directory?
     local_file = "#{dir}/#{file}"
     remote_file = remote_path + local_file.sub(local_path, '')

   ssh.sftp.upload(local_file, remote_file)

 end

您的box.ru 缺少require 'find' 行：

require 'find'

puts 'connecting to box...'
Net::SSH.start( host, user, :password => pass ) do|ssh|
result = ssh.exec!("cd #{remote_path} && ls")
 puts result
   ssh.sftp.connect do |sftp| 
 puts 'Checking for files which need updating'
 Find.find(local_path) do |file|
     next if File.stat(file).directory?
     local_file = "#{dir}/#{file}"
     remote_file = remote_path + local_file.sub(local_path, '')
 # ...
