Installation of aswf-docker - yaml issue

[hodoulp]

To use the ASWF docker images, I installed the aswf-docker utility following the steps explained here. Even if it successfully installs the tool (i.e. aswf-docker is working fine), it reports an error around yaml during the installation:

1. git clone https://github.com/AcademySoftwareFoundation/aswf-docker
2. cd aswf-docker
3. python3 setup.py install

The installation is on macOS 10.15.7 with docker 20.10.7

Looks like an wheel/pyyaml issue: aws/aws-cli#4243
Upgrading the packages should fix that. I was planning on upgrading to python 3.9 soon so hopefully that will fix that issue.
Did you try with pipenv?
Also, you can now run pip install aswfdocker but I've only tested it on windows and linux, not macs...

Latest version of aswfdocker on PyPi might be worth another try as I upgraded quite a few dependencies

Having just run into something similar on Ubuntu, the pyyaml package (optionally?) depends on libyaml and its yaml.h header file. On Ubuntu:

sudo apt install libyaml-dev

did the trick, I suspect on macOS you would want to do:

brew install libyaml

(assuming you already have Homebrew installed).
