Hello,

I am sorry but your request is not very clear. If you deployed it without a virtual env have you tried just setting it up? I would recommend reviewing the following guide that shows how to deploy a flask app, specifically how to install flask and setup the virtual env. You can find that here

If this doesn't help, please be a bit more specific on exactly what problem you are having as itn's not entirely clear what you are trying to do and the problem you are having.
