但我一直在犯这样的错误：

Neo.DatabaseError.General.UnknownError: Found no solution for block with size 8,
Vector() were the selected candidates from the table IDPPlanTable(numberOfPlans=63, largestSolved=6)

您可以尝试使用

EXPLAIN

运行它，您将得到相同的错误（如果不是，那么我认为这是一个bug或其他原因）
以下是github中公开的问题：
更新

我试图在更好的计算机上运行它，但它没有给出任何错误，但当我尝试使用更大的密码时，我得到了错误。
