Cannot Create A Virtual Environment

I've recently changed my OS to windows 10 and setup anaconda 3. The problem is that in Anaconda Navigator (in the Environment tab) when clicking on the create button to make a new

Solution 1:

python -m venv ./venv

you are mixng conda virtual environments with virtualenv virtual environments, hence all the confusion:

Could not find conda environment: venv

there is no conda enviroment venv, you have never created one.

In short:

When using conda, don't use virtualenv, insted use

 conda create -n venv

to create a virtual environment and

conda activate venv

to activate it
