Application installed by NPM (eg File C:\Users\name\AppData\Roaming\npm\ng.ps1) cannot be loaded because running scripts is disabled on this system

Question

When running commands installed by npm (i.e. yarn, ng, etc.), I receive the following error:

File C:\Users\<username>\AppData\Roaming\npm\<application> cannot be loaded because running scripts is disabled on this system.

where <application> is one of the commands installed by npm (i.e. yarn, ng, etc.)

How can this issue be resolved?

I just try this command in VS terminal(PowerShell) and my problem has been solved

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope CurrentUser

note : don't change CurrentUser to your username
edit : you can follow this link for changing the visual studio code terminal to cmd.exe instead of PowerShell and it will work without any security issues. https://blog.jongallant.com/2017/02/vs-code-integrated-terminal-powershell-default-change-to-cmd/

I had an issue with calling `yarn` from my powershell term in Visual Studio Code. Don't change "CurrentUser" to your username. – Eric Milliot-Martinez Feb 02 '21 at 04:13
This worked for me to solve the ERROR:
\ ```truffle : File C:\Users\Rain - Blockchain\AppData\Roaming\npm\truffle.ps1 cannot be loaded because running scripts is disabled on this system.``` I was trying deploying contract on rospten testnet. – Deepak Bhavsar Feb 18 '21 at 05:32
why you bypass the security, I hope you know the behavior of the command – Viplav Soni Feb 27 '21 at 09:46
for me it works in powershell not cmd – MonirRouissi Jun 19 '21 at 14:05

This does not work in `CMD`. it will work with `PowerShell` (Admin). Hope this will help to someone :-) – Saad Abbasi Jul 03 '21 at 05:07
