I followed the instructions for installing localstack running the following command:
`python3 -m pip install localstack`

Then, I ran localstack:
`python3 -m localstack.cli.main`

Which throws the following error:
`ImportError: cannot import name 'Literal' from 'typing' (/usr/lib64/python3.7/typing.py)`
