PSScriptRoot is null

Error

There is no error message, but $PSScriptRoot is empty/null.

Cause

This occurs because you are using ISE and when ISE is launched, $psISE is created and can be used to determine the current path of the ISE instance. This was introduced in version 3.0.

Solution

• If you want to get the path in either shell or ISE you could use something like this:

If ($GLOBAL:psISE) {
     Split-Path -Path $GLOBAL:psISE.CurrentFile.FullPath        
} else {
     $GLOBAL:PSScriptRoot
}
