When I used the command virtualenv venv to create the Python virtual environment, the following error occurred:
D:\Flask>virtualenv venv
Using base prefix 'd:\\APP\\python'

  Complete output from command D:\Flask\venv\Scripts\python.exe - setuptools pip wheel:

I googled it but didn't find a solution. Does anyone know how to deal with it?
