bug: fail to build ping-pong SC

[getlarge]

On MacOS Ventura - Intel, I fail to build the smart contract when running mxpy build contract. Any idea what could go wrong? Being unfamiliar with python, I have no idea what could be wrong with asyncio

The errors logs:

Hey @getlarge , This is a mxpy issue, therefore I will move the issue there -> follow it here: mx-sdk-py-cli.

A fix will be available ETA 15.03.2023 but until then you may use sc-meta. This is the way to go for building SCs, instead of mxpy if you have python > 3.10.

At the time of writing this issue, I wasn't sure if that was related to the tutorial setup, but you're right, as creating an empty smart contract and trying to build it led to the same error. So should this issue be closed ?

Thanks for pointing me to sc-meta, I haven't gone far enough in the docs to see it.

Thank you for the report!

Will be fixed by https://github.com/multiversx/mx-sdk-py-cli/pull/241.
