gulp : File is not digitally signed. during gulp serve

Problem

I was trying to create SPFx solutions and when I try to debug the solution using gulp serve command I got the below error “gulp : File C:\Users\suhail\AppData\Roaming\npm\gulp.ps1 cannot be loaded. The file C:\Users\suhail\AppData\Roaming\npm\gulp.ps1 is not digitally signed.”

Solution

To fix the issue  we will have to run the below command.

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

This command sets the execution policy to bypass for only the current PowerShell session, when you open again you may need to run again.

Happy SPFx building
