Ruby Net::SFTP 不工作，即使在它自己的示例代码中也是如此

Question

尝试使用 Net::SFTP，版本 2.05(似乎是最新的)。但它甚至在自己的示例代码上也失败了(下面，来自 http://net-ssh.rubyforge.org/sftp/v2/api/index.html )。域、用户和密码与我手动登录时使用的相同。当我能走到那一步时，我会改变路径。

Net::SFTP.start('ftp.domain.com', 'user', :password => 'password') do |sftp|

    # upload a file or directory to the remote host
    sftp.upload!("/path/to/local", "/path/to/remote")

    # download a file or directory from the remote host
    sftp.download!("/path/to/remote", "/path/to/local")

    # grab data off the remote host directly to a buffer
    data = sftp.download!("/path/to/remote")

    # open and write to a pseudo-IO for a remote file
    sftp.file.open("/path/to/remote", "w") do |f|
      f.puts "Hello, world!\n"
    end

    # open and read from a pseudo-IO for a remote file
    sftp.file.open("/path/to/remote", "r") do |f|
      puts f.gets
    end

    # create a directory
    sftp.mkdir! "/path/to/directory"

    # list the entries in a directory
    sftp.dir.foreach("/html") do |entry|
      puts entry.longname
    end
  end

它卡在第一行，回溯在下面(第 14 行是 Net::SFTP.start 行)...

当我在 Perl 中使用 Net::SFTP 时，我遇到了类似的问题，因为它的 ssh 路径设置不正确。你能检查 SSH 是否在路径中吗？我知道答案与 Ruby 无关，但建议这是一般性观察。
