Can not build docker image - Flask assets fail with errors

[croessner]

Hi,

I try to build a docker image from current master branch, which unfortunately failes with errors:

From within the unpacked source folder I run the following command:

docker build -t powerdns-admin:latest -f docker/Dockerfile .

After a while, messages like these occur:

I really would love the docker version again :-)

Thanks for helping and for that great project!

Ya, I noticed this issue. Although it doesn't break the docker build process but still better to fix it. Upgrading the pip package solves the issue.
