python – Tengo un problema intentando hostear mi código en Heroku

el caso es que estaba haciendo un bot de discord e quise hostearlo en la nube con la página Heroku. Todo iba bien hasta que, cuando le dí a deploy branch el código me dió en siguiente error:

-----> Building on the Heroku-20 stack
-----> Using buildpacks:
       1. heroku/python
       2. heroku/python
-----> Python app detected
-----> No Python version was specified. Using the same version as the last build: python-3.9.4
       To use a different version, see: https://devcenter.heroku.com/articles/python-runtimes
-----> Requirements file has been changed, clearing cached dependencies

Creo que el problema está relacionado con las dependencias, las cuales están en un archivo txt con el nombre de requirements, mismo que la página te pide antes de subir tu código, sin embargo ya he cambiado varias veces las mismas y sigo sin obtener resultados positivos.

Este es el contenido de mi archivo requirements.txt:
discord
wikipedia
googletrans
setuptools
dotenv

Aprecio mucho su colaboración!
