Question

Answer 1

With Anaconda you have conda for enviornment handling. Have a look at conda enviornments and how to install packages with conda.
In the Anaconda Prompt with Admin rights you can do:

conda create -n py39 python=3.9
activate py39
conda install -c conda-forge opencv

Then you can use your new env in any command prompt with:

activate py39

Answer 2

Maybe it's better to use:

• anaconda prompt

  In windows 10 search box search for anaconda prompt

• python virtual environment.
