Plyvel not linked correctly to leveldb in MacOS

[julianmrodri]

Issue

Getting the following error when trying to import plyvel in Python console after installing leveldb.

Additional information and context can be found in this issue (ConsenSysDiligence/mythril#1509). Redirected from their repo.

Steps I followed to install (which include leveldb).

brew update
brew upgrade
brew tap ethereum/ethereum
brew install leveldb
brew install solidity
pip3 install mythril

But after installation if I try to run simple plyvel import in Python console I get this error.
It is likely the leveldb packages aren't linked to plyvel correctly?

No.. had to move to another installation method using Docker.

It looks like this issue is a duplication of #114. In the latest version (1.23), it disabled RTTI, that causes this issue.
I resolved the problem by uninstalling homebrew version and install leveldb 1.22 from the source code.

To solve Symbol not found: __ZTIN7leveldb10ComparatorE on MacOS:

brew uninstall leveldb
# Fetches the LevelDB v1.22 formula.
wget https://raw.githubusercontent.com/Homebrew/homebrew-core/e2c833d326c45d9aaf4e26af6dd8b2f31564dc04/Formula/leveldb.rb
brew install --formula ./leveldb.rb
export LIBRARY_PATH="$LIBRARY_PATH:$(brew --prefix)/lib"
export CPATH="$CPATH:$(brew --prefix)/include"
# Use pip3 maybe.
pip install plyvel

There are a few noticeable setups with my device:

1. I'm using the Python installed with Homebrew, rather than from /usr/bin/python3.
2. I've aliased python to python3, and pip to pip3.
3. I'm using Python 3.10.

pip install plyvel

There are a few noticeable setups with my device:

1. I'm using the Python installed with Homebrew, rather than from `/usr/bin/python3`.

2. I've aliased `python` to `python3`, and `pip` to `pip3`.

3. I'm using Python 3.10.

I guess brew removed old version as now i have this in console output:
