I installed browser-sync using : npm install -g browser-sync as well as added the module as dev dependency using: npm i --save-dev browser-sync.

But when I try to do the following command the create file : browser-sync init , I'm getting the following error:

browser-sync : File C:\Users\aksha\AppData\Roaming\npm\browser-sync.ps1 cannot be loaded. The file C:\Users\aksha\AppData\Roaming\npm\browser-sync.ps1 is not digitally signed. You cannot run this script on the current
