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。但我这辈子都无法恢复它。
rethinkdb restore [file] 和 rethinkdb import [file] 不起作用，但经过一些谷歌搜索后我发现我必须安装 python 工具 (pip3 install rethinkdb)。我这样做了，但现在出现此错误：
% rethinkdb restore rethinkdb_dump_2020-11-21T20:35:20.tar.gz > bug.log

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