Error deploying Streamlit app "Could not find a version that satisfies the requirement StringIO"

Question

I'm new in the use of streamlit. I have an app and it work in the local way. But I tried to deploy this app and it seems that the library "io" isn't recognize. Does anyone know how to fix it ?

I've already tried several things but it doesn't works.

My repo is here :https://github.com/m-moriss/Data_challenge_RAKUTEN

I use "io" librairy in "donnees.py" and the I also put this librairy in the requirements.txt file.

Here the error message

Answer 1

StringIO is a class of the module io and not a module itself.

Also, you doesn't need to include io in your requirements.txt since it's a python's built-in.
