Thank you so much for this! I ran into some problems while following these steps, specially because I didn't have PATH configured correctly. But after some googling and researching (and some screaming as well) everything worked, so again, thank you!

[@SMUS16475]

Thanks for the instruction. I'm taking a course this semester that specializes in developing web apps using the Flask back-end framework, and I think this video was very useful in giving me a basic rundown on the Flask app setup in VS Code.

go to your environment folder where you did the cmd "venv yourenvironmentname" then locate the scripts folder and locate activate.bat so in your cmd it should look like c:\user\yourname\yourenvironmentnamefolder\scripts\activate.bat then run it in cmd. now it should look (yourenvironmentnamefolder) C:\Users\yourname\yourenvironmentnamefolder
