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?
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.

I downloaded OpenCV folder from GitHub and followed the ReadMe instruction to build it for ios.
After use python opencv/platforms/ios/build_framework.py ios command I have the following error:

What I have to do to fix it?
If someone in the future will have the same problem.
This problem was in the master branch, downloading branch 2.4 and adding CMake at PATH the build process go well
I also encountered the same problem.
In the master branch or 3.4 branch or 2.4 branch.
But after installing cmake, it will be fine.
In the 2.4 branch error message will show :
/bin/sh: cmake: command not found

Am I missing something? I have Mercurial installed and am able to clone the build tools repo.
Judging from the error message, /usr/bin/firefox couldn't be started because:
OSError: [Errno 2] No such file or directory
ABP Crawler requires Firefox to be installed, it will automate Firefox in order to collect data. If Firefox is actually installed, maybe the path is /usr/local/bin/firefox or something similar. You can run which firefox from the command line if you aren't sure.
How do I run/install this: https://github.com/kevmoo/kbuild?
I installed the dependencies and tried to execute the bin/kbuild Python script, but it's giving me this error:
Traceback (most recent call last):
File "kbuild/bin/kbuild", line 12, in <module>
BREW_PREFIX = subprocess.check_output(['brew', '--prefix']).strip()

raise child_exception OSError: [Errno 2] No such file or directory
My guess is that this tool was intended for OSX and Homebrew and that's why it's choking. I just wasn't sure based on the minimalist installation instructions.
Line 12:
BREW_PREFIX = subprocess.check_output(['brew', '--prefix']).strip()
is explicitly trying to run 'brew' in the shell, so yes I'd say it is written only for OSX.
I'd suggest you wait for your Issue to be answered on GitHub, or try modifying it yourself. It seems brew is only being used to check for available compilers.
I'm working with a set of scripts aimed at modifying an android app, the github repo located here: Ingress Broot Mod. I installed Python 3.2, then installed PyYAML 3.10. I moved on to follow the build instructions and "Import Ingress apk using import_apk.py script."
Specifically, I typed: B:\GitHub\ingress-apk-mod\bin>python import_apk.py "B:\com.nianticproject.ingress-1.apk"
At which point this error pops up.

The closest I could find was Unable to run call subprocess method using python 3.2.
Is this an easy fix; if not, what steps should I take to fix this problem?
This is my first time using python - could this possibly stem from improperly installed Python (did I miss a step?)
I am trying to build adblockplus from this link. When I issue the command:

Am I missing a package? Any hint on what the problem could be will be much appreciated.
The stack trace makes it clear that the issue is caused by the following line:
(result, dummy) = subprocess.Popen(['hg', 'id', '-n'], stdout=subprocess.PIPE).communicate()
If you look at the subprocess package documentation, this line is trying to run the hg id -n command (get numerical Mercurial revision). Apparently, the Mercurial command line tool isn't present on your system (a possibility that this build script didn't consider) so it fails.
Disclaimer: I happen to be the one who wrote this script and I fixed this bug now. Mercurial isn't essential for the build, the revision number is pretty much only necessary to determine the output file name.
