使用 Pyinstaller 创建单个 Flask 可执行文件

Question

I have created a flask application which runs on a local server. I need to turn it into a single executable file using pyinstaller.

The following is my directory structure for my flask application in PyCharm:

Form
- migrations
- venv
- - app
- - - static
- - - templates
- - - __init__.py
- - - forms.py
- - - models.py
- - - routes.py
- microform.py
- config.py
- app.db

I tried running

pyinstaller -w -F --add-data "C:\Users\test\PycharmProjects\Form\venv\app\templates;templates" 
--add-data "C:\Users\test\PycharmProjects\Form\venv\app\static;static" 
--add-data "C:\Users\test\PycharmProjects\Form\migrations;migrations" microform.py

Everything compiled properly, and the flask application works except for the database that I created. I am unable to login because but the flask application gives me the following error when I input my username and password:

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) unable to open database file
(Background on this error at: http://sqlalche.me/e/e3q8)

Everything works fine when I run it in PyCharm, but when I try opening it by clicking on the executable file from pyinstaller it just gives me the above error whenever I try to login?

Appreciate any help or advice. Thanks.

You should run the pyinstaller command with your main file, where you call all of your functions and classes.
