error while trying to install yarn in vscode when i had earlier been using npm

Question

This is the error message

yarn : File C:\Users\Admin\AppData\Roaming\npm\yarn.ps1 cannot be loaded 
because running scripts is disabled on this system. For more 
information, see about_Execution_Policies at 
http://go.microsoft.com/fwlink/?LinkID=135170.
At line:1 char:1
+ yarn
+ ~~~~
    + CategoryInfo          : SecurityError: (:) [], PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess

This seems relevant: [PowerShell says "execution of scripts is disabled on this system."](https://stackoverflow.com/questions/4037939/powershell-says-execution-of-scripts-is-disabled-on-this-system) — DBS, May 17 '22 at 12:46

For those who are not aware of how to solve this error using Windows PowerShell

Open PowerShell (Run As Administrator)
Check the current execution policy using this command

    Get-ExecutionPolicy
    # You should get 'Restricted'

Run this command to make it 'Unrestricted'

  Set-ExecutionPolicy Unrestricted

Check again whether execution policy changed by running this command
```
Get-ExecutionPolicy
You should get 'Unrestricted'
```
Now try to run nodemon on your project

   nodemon 'filename.js'

Hope this would be helpful
