Error deploying streamlit app, when I want to include pypsa package in my requirements.txt

This is how my requirements.txt file looks like:
matplotlib>=3.7.1
pandas>=2.0.0
plotly>=5.3.1
streamlit>=1.27.0
openpyxl>=3.1.2
Pillow>=9.4.0
pypsa

I am not able to include pypsa, because streamlit gives the following error, when installing build dependencies:

I am not sure why this problem appears, yesterday everything was working fine, but today it is not able to deploy due to this problem.

Which version of Python are you using to deploy your app? I ran your requirements through pip with --dry-run and it resolved in Python 3.11, 3.10, and 3.9 but not in Python 3.8.
