迷航包装误差

Question

我在试着装新的流浪汉底座。当我这样做的时候，我会得到这个错误。

Answer 1

在方法ssh_info中，在第318行之后缺少一个end语句：

你的代码：

  # If we have a private key in our data dir, then use that
  if !@data_dir.nil?
  data_private_key = @data_dir.join("private_key")
  if data_private_key.file?
  info[:private_key_path] = [data_private_key.to_s]
  end

它应该是什么：

  # If we have a private key in our data dir, then use that
  if !@data_dir.nil?
    data_private_key = @data_dir.join("private_key")
    if data_private_key.file?
      info[:private_key_path] = [data_private_key.to_s]
    end
  end    # <-- this is missing

这种类型的错误总是在文件的最后一行中得到报告，因为它希望关闭块并到达文件的末尾，而没有获得足够的end语句。
