Exception thrown when starting localstack

Question

I'm doing this on mac, and before I start localstack, I ran pip install --upgrade localstack. Then, I did localstack start. Then I got below exception

I actually checked if there's any process is listening on 4564 by lsof -n -iTCP:4564 | grep LISTEN, but nothing returned.

Try this:

DEBUG=1 localstack start

In the logg before erroring out You may find a path containing: localstack.ddb.zip (replace some_path below) Remove that file and also remove the dynamodb package from localstack/infra.

rm -f /var/folders/some_path/localstack.ddb.zip
rm -rf /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/localstack/infra/dynamodb/

Now you can try localstack start again.

Furthermore: I am seeing the same issue when I run in docker, but there I can't remove anything since the container is created from an image on every compose-up.
