I messed around with trying to install 'pkg-config' and adding it to my path, but that didn't seem to help. What is going on?

[asherp]

I was able to install pkg-config using miniconda

conda create -n myenv python=3.9
conda activate myenv
conda install -c conda-forge pkg-config
pip install --use-pep517 nostr==0.0.2

Check this Dockerfile https://github.com/raymonostr/nip57-server/blob/main/Dockerfile - you need pkg-config and build-essential to build the secp256k1

[cromatikap]

I got a similar issue from a Docker container, I fixed it with those packages installation:

RUN apt-get update && apt-get install -y pkg-config libsecp256k1-dev build-essential

On Mac you can do brew install pkgconfig
