Streamlit App:
https://pyledger.streamlit.app/

Github Repo:
https://github.com/atbreen/PyLedger

Error:
ModuleNotFoundError: No module named ‘matplotlib’

Streamlit Version: 1.29.0

Python Version: 3.11.2

This application was deployed and working fine until I added a chart using matplotlib to it. I tried adding the requirements.txt file and my app still will not deploy. This is for a final project for college and I thought I was going to be done tonight (lol). It’s due next Thursday 12/7/2023.

Any help would be greatly appreciated.

I can’t find a requirements file in your repo.

I am facing the same problem.
I am trying to deploy my app on streamlit. Once I added the matplotib, it gave an error.

 Running setup.py install for matplotlib did not run successfully.

  │ exit code: 1

      IMPORTANT WARNING:

 note: This error originates from a subprocess, and is likely not a problem with pip.

There is not enough context, my guess is that the python packages you are installing are too old for your python. Why did you chose those particular versions?

I ended up just not using matplotlib for this project :woman_shrugging: still not sure what the problem was.

I removed matplotlib and used a different graphing library. It was deploying fine without the requirements file before so I removed it. Works now.
