Now that you have pip installed and a command prompt open installing virtualenv to our root Python installation is as easy as typing:

pip install virtualenv

Now we have virtualenv installed which will make it possible to create individual environments to test our code in.

This is the kit and caboodle of this guide.

pip install virtualenvwrapper-win

Excellent! Now we have everything we need to start building software using python!

I'll call it HelloFlask

Not working

mkvirtualenv HelloFlask

py -m venv env

env\Scripts\activate

pip install flask

set FLASK_APP=app.py

set FLASK_DEBUG=1

flask run
