python-3.x - 在 MacOS Big Sur 上恢复 RethinkDB 备份

问题描述

升级到 MacOS 11（“Big Sur”）后，我的本地 Rethink 数据库消失了。不过没关系，因为我有备份。但我不能，为了我的生命，恢复它。

rethinkdb restore [file]并rethinkdb import [file]没有工作，但经过一番谷歌搜索后，我发现我必须安装 python 工具（pip3 install rethinkdb）。我这样做了，但现在我收到了这个错误：

% rethinkdb restore rethinkdb_dump_2020-11-21T20:35:20.tar.gz > bug.log
Traceback (most recent call last):

TypeError: cannot pickle '_thread._local' object

我尝试卸载 RethinkDB 和 Python 工具并重新安装它们。同样的结果。
