Try clearing the cache and/or running with sudo:

[sudo] npm cache clean -g
[sudo] npm install tower -g

These random errors are usually b/c of the npm cache.

Thanks for the quick reply. It worked like an chram.

Eagerly waiting to contribute something to this project.

This project is just awesome.

npm cache clean -g Thanks, this worked for me too, had a similar problem, though not related to 'tower'
