我正在尝试使用Linked List为我的某个驱动器编制索引。每个节点包含路径的变量和该特定路径中所有文件夹和目录的list。但是，我查看了错误，并且在达到 164（读取注释）的大小之前，它没有显示任何错误。大于此，它提出了前面提到的错误。链表包含大约5500个节点。
注意：我尝试在程序开头使用 sys.setrecursionlimit(x) ，它可以达到757个节点，以便成功转储对象通过设置 pickle 来加载 sys.setrecursionlimit(4558) 。增加此限制， linklist 对象中的节点总数阈值没有变化，可以成功转储到文件中而不会出现标题错误。
其他注意事项：我将 import 包从 pickle 替换为 {{1} 和 cPickle 可以作为对象存储到文件中的节点的阈值数量急剧增加到 4470 。我已相应更改了我的代码。
这是我的代码，它进一步简化，以便用户使其可读并且基本上坚持这一点。我已经省略了许多重要的函数和代码部分，据我所知，它们与错误无关。

的对象存储到164或更小时，这是堆栈跟踪。 在加载文件之前缺少output.close（）。
