Activate venv (Python 3.7.2) for Windows

Try using the terminal to navigate to the folder that contains your virtual environment using the change directory (cd) command. Once there, try typing:

source ./venv/Scripts/activate

Also, try opening the venv folder and make sure your activate file is in the 'Scripts' folder and not the 'bin' folder. When I create a virtual environment, I use:

source ./venv/bin/activate
