Bug: Python error: RuntimeError: Opening RocksDB #434

Describe the bug

Hello,

I try to use embedded RocksDB data engine with ustore package in Python (3.10) and I get an error: RuntimeError: Opening RocksDB

I try to use an example from the Readme:

from ustore import rocksdb

db = rocksdb.DataBase('/home/user/tmp/try_ustore/rocksdb/')  # the error is here
db.main[42] = 'hello!

The directory /home/user/tmp/try_ustore/rocksdb/ is exist.

If I use open=False I get an error: RuntimeError: DataBase is uninitialized.

db = rocksdb.DataBase('/home/user/tmp/try_ustore/rocksdb/', open=False) 
db.main[42] = 'hello!  # the error is here

There are no any logs or debug info, so I do not understand what is happening and why the database cannot be created and opened. Maybe are some additional dependencies needed, or do I need to set some config? But in the Readme or the documentation I cannot find anything about this.

Steps to reproduce

# pip install ukv

from ustore import rocksdb

db = rocksdb.DataBase('/path/to/db/directory/')
db.main[42] = "hello"

Expected behavior

A database is created/opened and can be used

UStore version

0.12.1

Operating System

Ubuntu 20.04, Mint 21.2
