Hi,

I’m trying to put my Python project with streamlit on the cloud, but I get this error all the time. I already have the requirements.txt. I’m on Windows 10 operating system.

Failed to build pycairo

ERROR: Could not build wheels for pycairo, which is required to install pyproject.toml-based projects

I’ve read about this Getting Started — Pycairo documentation 71. But I don’t understand for Windows what packages I have to install

Hi @PARODBE,

Thanks for posting!

Please try adding this to a packages.txt file within your directory based on the pycairo docs:

libcairo2-dev
pkg-config
python3-dev
