It was stated in the docs: https://docs.particle.io/guide/tools-and-features/cli/#installing

If you experience permission errors, you have two options: change the permission to npm's default 
directory or change npm's default directory to another directory (preferred choice on a multiuser 
environment). Both options are documented here.

For reference: https://docs.npmjs.com/getting-started/fixing-npm-permissions
