tsc.ps1 cannot be loaded because running scripts is disabled on this system

On PowerShell, I got the error message when executing tsc. This never happened before.

I am not sure should I mingle with the PowerShell security settings to rectify this such as based on this one: PowerShell says "execution of scripts is disabled on this system."

Update

This is a new intended feature by npm to use ps1 scripts. A question has been raised in their repo: https://github.com/npm/cli/issues/470

Solution 1:

You can run this in PowerShell command. Be sure to run it as administrator:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

Solution 2:

Use tsc.cmd instead of tsc. For example:

tsc.cmd -v
tsc.cmd --init

Solution 3:

Open Command_form : windows + R

Type : Powershell

Then type : set-executionpolicy remotesigned

And select option : A
