Expected behavior
install cleanly

logs

environment details
node 10 & 12. In used node's docker image in the steps to reproduce. I came across this issue running ubuntu 16 and was able to replicate exactly in docker.

Additional context
Older versions still work. I was able to successfully install 1.7.1:

docker run -it node:12-alpine sh -c "apk add python && npm install -g @aws-amplify/[email protected]"
