Cannot find basic libraries when deploying the app in the community cloud?

I’m trying to deploy my first app. The app works fine on my local machine but I receive errors I cannot make sense of when deploying.

Streamlit app: https://hharleman-fred.streamlit.app/
GitHub repo: GitHub - hharleman/fred: FRED financial data to compare economic metrics at the end of Bidens term to Trump's second term.

It seems like every time I try to deploy, I get an import error for one of the packages I’m importing. This time it was plotly. Previously it was sqlalchemy.

ModuleNotFoundError: No module named ‘plotly’

That often means that the package was not installed. Install it and the error should go away.

Add the libraries to your requirements.txt. I see plotly missing
