[您的内容]

The documentation for functools.cache states that it's only available from Python 3.9 onwards. If you're using an earlier version then the documentation also states that it's the same as using lru_cache(maxsize=None), so that's probably your best option.

Thanks, this bug and another known bug will be fixed in this week after #580 be merged.

[SeaHOH]

I commit the changes, but sorry there is no time to review, so put merging off to next week.
