I don't really understand what this means, and I'd like some assistance installing a package and trying to fix this error. Thanks! -Shane
EDIT: I found near the beginning the text 'Command errored out with exit status 1'
EDIT: I have installed libffi-dev.
Solved by upgrading pip to pip3 using sudo apt-get -y install python3-pip.
Looks like you may need to install libffi-dev. I'm not sure your distro, but it'll be there. Distro is raspbian.
Install with:
apt-get install libffi-dev
There are other questions that looks similar since they have the _ctypes issue, but I won't mark this as a duplicate since your question is exactly the same. I think the underlying root cause is probably the same. See here and here.

pip cannot find build dependencies

I am trying to install some python libraries using
pip install -r requirements
The file looks like:

matplotlib
pandas
networkx

It was initially giving errors for C++ build tools, but after installing those using the visual studio installer I get the following error.

Edit:
Appears gcc is not included in the alpine base image.
I resolved this issue by using FROM python:3.6-slim instead.
