Cannot run command pyb from Pybuilder in Anaconda prompt

I wanted to reactivate an old python project I worked on two years ago.

I wanted to recreate the same working conditions with one difference: when I developed at the time i worked on Ubuntu WSL (win10) with virtualenvs. Now I want to work directly from windows 10 using Anaconda.

commands in Anaconda prompt (admin rights) I entered

conda create -n env python=3.6
conda activate env
pip install pybuilder==0.11.17
pyb

this is where the error occurs. I get it in german but it's s.t. like "The command "pyb" is either spelled wrong or doesn't exist"

Note that all my relevant files for the project (namely build.py) are already present and I execute the command in the correct directory. Although I don't think that's the issue since command is not even recognized.

pip list confirms pybuilder is installed correctly and where python tells me the first python it uses is from the correct environment.

I strongly assume it has s.t. to do with Anaconda, since i was able to successfully redo it under Ubuntu WSL (win10) conditions again.

Edit: i made it work using the absolute path to the conda environment and executing pyb_.exe. However the file pyb* is present too. I'd still be interested to know why the anaconda prompt is not able to execute it.

Appreciate any ideas on how to solve this. Cheers!

Solution

I'm going to close this as I have found a satisfying solution:

I tested my code with updated packages (pip) and it still worked.
pybuilder==0.13.3
tried pybagain in the anaconda prompt and it executed without problems

since this is merely an issue with outdated software I'll mark this as answered
