Had to downgrade protobuf (v4 -> v3) to run Manticore

[ChmielewskiKamil]

Summary of the problem

This is my first-ever use of Manticore so please take it with a grain of salt.

I've installed Manticore in a virtual environment with Python 3.9.13 and run Manticore on a contract with manticore token.sol. After that I get the following error: TypeError: Descriptors cannot not be created directly.. The actual log is in the any relevant logs section below.

I've managed to fix the issue by downgrading the protobuf package to version 3.20.1 (as mentioned in #2558) by running pip install protobuf==3.20.1

I've noticed that during the installation of Manticore (pip install manticore) it is using the cached version of protobuff:

Collecting protobuf
  Using cached protobuf-4.21.9-cp37-abi3-macosx_10_9_universal2.whl (483 kB)

I've deleted the virtual environment and repeated the installation process 2 times with the same result.

I am aware of the fact that the protobuf v4 package is not supported yet (as there is #2559) but for a beginner user like me, this was a little headache to fix. I was not aware of the existence of the protobuf in the first place 😅

I am not sure if this is the expected behavior or not.

Thanks!

Manticore version

Version: 0.3.7

Python version

Python 3.9.13

OS / Environment

macOS Monterey Version 12.6 Apple M1 chip

Dependencies

crytic-compile==0.2.2 cytoolz==0.12.0 eth-hash==0.5.1 eth-typing==3.2.0 eth-utils==2.1.0 future==0.18.2 intervaltree==3.1.0 manticore==0.3.7 ply==3.11 prettytable==3.5.0 protobuf==3.20.1 pyevmasm==0.2.3 pysha3==1.0.2 PyYAML==6.0 rlp==3.0.0 sortedcontainers==2.4.0 toolz==0.12.0 wasm==1.2 wcwidth==0.2.5 z3-solver==4.11.2.0

Step to reproduce the behavior

1. Create virtual environment python3.9 -m venv manticore-env
2. Activate the environment source manticore-env/bin/activate
3. cd into the contracts folder
4. Run Manticore on a target contract (in my case manticore token.sol)

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 5. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Are you installing Manticore from PyPI or the latest commit on this repo? I tried to reproduce your results using the latest commit of Manticore, and it correctly removes the newer protobuf:

If you're using Manticore from PyPI, then I can reproduce your issue, and we'll need to create a new release of Manticore to fix it. Thank you for the report!

I am installing the PyPi version.
