Cx_freeze packaging tortoise-orm application error 'PackageNotFoundError: No package metadata was found for tortoise-orm'

[opsboy]

I wrote a web service using fastapi+tortoiser orm, and then packaged it using cx_freeze. After successful packaging, I ran the exe file and received the following error message:

• cx_Freeze version 7.2.0
• Fastapi versin 0.112.0
• Tortoise-orm version 0.21.6
• Python version 3.10

I'm a little confused by your setup, but first, I need a sample application to test. I found this example, which can be a test base. I want to run it using Python, and then build it with cx_Freeze to reproduce the error. I used these requirements: pip install "fastapi[standard]" tortoise-orm uvicorn But I got this error: ModuleNotFoundError: No module named 'routers' Can you suggest the correct requirements?

@marcelotduarte You can use this template to test it.
