Tried to deploy my railway app via django. But it wont post and crashes instead. No idea why my railway app keeps crashing. Only error I see is for TK, which i verified is installed. What is the problem? Here is the log:

Tried redownloading TK which did not help.. Reinstalled python which did not help.

  • the environment you are trying to run this app in, has no module named '_tkinter' – Umair Ayub Apr 21 '23 at 07:01

  • In your own words, why do you think it should be possible to use turtle graphics from within a Django railway app? How exactly do you intend for the graphics to be drawn? Should they appear in the web page contents somehow? – Karl Knechtel Apr 28 '23 at 21:24

I hope you used a virtual environment.

Freeze you requirements with pip freeze > requirements.txt

The server on which you want to deploy your app needs to know which requirement are needed, those will be installed when deploying.

  • I did both those things. The server will initially say all is good and that the app is ready. Then it will crash two minutes later. – texinterport Apr 21 '23 at 14:21

  • What does it mean it crushes? Have you been able to open the website or does it crush while deploying it? I have the feeling it is related to Tkinter, look at his https://stackoverflow.com/q/5459444/16175571 – GCMeccariello Apr 21 '23 at 14:59
  • railway says it is good to go but when i click on the link I get a server error. And then the link turns red and says it crashed. Never get a chance to see the application – texinterport Apr 22 '23 at 01:26
  • That usually happens if the libraries are not installed, or the settings for connecting to the DB are wrong. It is really hard to say what the problem is. I would suggest to set `Debug=True`, deploy it again and check the error message you get from Django. – GCMeccariello Apr 22 '23 at 07:30
