Zola on RPi

Want to install Zola on RPi4.
Installed it through snap as instructed here…Install zola on Raspberry Pi using the Snap Store | Snapcraft

Running ‘zola --help’ in terminal shows that v0.13.0 is successfully installed

Running ‘zola init helloworld’ in terminal creates dir helloworld

After moving into /helloworld when ‘zola serve’ is run get error …“no port available”

How do I resolve this??..I know the default port used by zola is 1111. How can I make this port available.
Any help is welcome as I am a newcomer to the “linux world”

Thank You

I figured it out…when installing snap I missed installing core pkg (sudo snap install core).
Now that it is installed all works like a charm.
