Answer 1

You can also try this: Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37 In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.

Answer 2

For Python 27

virtualenv -p C:\Python27\python.exe django_concurrent_env

For Pyton36

 virtualenv -p C:\Python36\python.exe django_concurrent_env
