How to convert flask project into executable .exe

Question

I need to convert my flask project into.exe

It's small project intended to run on local browser (offline).

When I run the exe script it tells me that flask has not been imported. It's not true as it works when fired directly from main.py. Seems like pyinstaller skips some libs. What can I do?

main.py

from app import create_app

if __name__ == "__main__":
    app = create_app()
    app.run()

app/ init .py

from flask import  Flask
SECRET_KEY = ""
UPLOAD_FOLDER = ""
MAX_SIZE = 500000

def create_app():
    app = Flask(__name__)
    app.config["SECRET_KEY"] = SECRET_KEY
    app.config["UPLOAD_FOLDER"] = UPLOAD_FOLDER
    app.config['MAX_CONTENT_PATH'] = MAX_SIZE

    from .views import views

    app.register_blueprint(views, url_prefix="/")

    return app

Command to pack pyinstaller -F main.py

main.exe error

Traceback (most recent call last):
  File "main.py", line 1, in <module>

run the pip show pip you will need the -p to point to the pip libs example

or

This is what my make file look like, I am using this for windows and linux
