In my first attempt I left the build command blank. It seemed to build successfully, and then the deploy log showed error:
ModuleNotFoundError: No module named '_tkinter'I am not even using Tkinter in my app. -
Second attempt I added a procfile with the line:
web: uvicorn --app-dir src nft_server:app --reloadin my repo and even the build failed.
My github repo: https://github.com/zubin-madon/NFTrees
To build locally this is what I do:
app.py - client side web application (transpiled files get put into ./src/target/)
(venv) $ transcrypt --nomin --map src/app.py
nft_server.py - FastAPI REST server
(venv) $ uvicorn --app-dir src nft_server:app --reload
http://localhost:8000
- I tried this article here: https://dev.to/mrcartoonster/fastapi-do-deploy-1h10
But the run command is failing me. Here’s what the article says:
Modify the Run Command setting to point to your application. For this example, my project is named
mysite. So the modified command would begunicorn --worker-tmp-dir /dev/shm --config gunicorn.conf.py src.main:app
I replaced src.main with src.nft_server as per my repo. The rest I kept the same. Build succeeded but deploy failed.

Hi there,
I’ve just forked your repo and tried to deploy it. It all worked as expected.
I can see that you’ve added the requirements.txt file just a couple of hours ago, have you tried deploying the app after the file was added?
The error that you are getting indicates that the first time you tried deploying the app you did not have the requirements.txt file in your repo.
Besides, for anyone who might come across this in the future, here are a few troubleshooting steps that might be helpful:
-
ModuleNotFoundError: No module named ‘_tkinter’: This is a common issue faced when deploying Python applications. ‘_tkinter’ is the standard Tcl/Tk interface module for Python. The issue can arise when certain libraries have a dependency on it, even if you aren’t directly using it. To address this, you might want to:
- Double-check your dependencies in
requirements.txtto see if there’s anything that might be pulling in Tkinter. - If you’re sure you don’t need Tkinter, you can safely ignore this error, but remember that if a library is trying to import it, that library might not work as expected.
- Double-check your dependencies in
-
Procfile: If you’re following the Heroku-style deployment (which DigitalOcean’s App Platform sometimes uses), the
Procfileis crucial. The format and contents should be correct. Given that you mentionedweb: uvicorn --app-dir src nft_server:app --reload, ensure theProcfileis at the root level of your repository and there are no typographical errors. Also, make sure there’s no additional whitespace. -
Use of
gunicorn: If you’re trying to usegunicorn, you must ensure it’s installed and listed in yourrequirements.txt. If not, the deploy process won’t know about it and you’ll receive the error “gunicorn: command not found”. Add it to yourrequirements.txt. -
Additional Tips:
- Make sure all the required dependencies for your project are listed in
requirements.txt. - If you’re using any environment-specific configurations, make sure they’re correctly set up in DigitalOcean’s App Platform.
Best,
Bobby
