[Bug] shims file ps1 sometimes $PSScriptRoot is empty string

[uuRRx0]

Bug Report

Current Behavior

When adding a tool like scoop-setup.ps1, after running the command scoop setup arg1, the value of $PSScriptRoot in the command_path method is a empty string.

Expected Behavior

Ability to correctly call the scoop setup arg1 method

Additional context/output

Possible Solution

When $PSSScriptRoot is a null character, you can add a fallback hard-coded path parameter, such as the post_install hook in the configuration below.

Windows version: 11

OS architecture: 64bit

PowerShell version: 5.1.22621.2506
