I'm trying to run the tests for the contract from this tutorial, https://docs.elrond.com/developers/tutorials/your-first-dapp/, but I'm stumbling upon the below error when running erdpy contract test

I've searched for a way to install mandos-test, but couldn't find anything useful. What am I missing?

Solution

  • TLDR: if running in a WSL environment, that might be the issue.

    Ok, I've managed to side-fix the issue.

    Initially, I was running Windows 10 and Ubuntu 20.04 using WSL2. After trying various solutions (e.g.: updates, reinstalling dependencies etc.) I've given up. I've removed the Ubuntu 20.04 WSL2 environment and instead went for having an actual Ubuntu 20.04 installation, alongside Windows 10 and dual booting between them. Everything ran smoothly in the new, standalone, Ubuntu environment. My guess is that some dependencies are either not installed or not properly configured in a WSL2 environment, but considering my current erdpy & elrond tech stack experience, I cannot confirm or pinpoint the exact root cause.
