relative path in Import-Module

Question

I have directory structure that looks like this:

C:\\TFS\\MasterScript\\Script1.ps1
C:\\TFS\\ChildScript\\Script2.ps1

What i want to do is

Answer 1

This worked for me:

$selfPath = (Get-Item -Path "." -Verbose).FullName
$dllRelativePath = "........"
$dllAbsolutePath = Join-Path $selfPath $dllRelativePath
Import-Module $dllAbsolutePath

Answer 2

When you use a relative path, it is based off the currently location (obtained via Get-Location) and not the location of the script. Try this instead:

$ScriptDir = Split-Path -parent $MyInvocation.MyCommand.Path
Import-Module $ScriptDir\..\MasterScript\Script.ps1

In PowerShell v3, you can use the automatic variable $PSScriptRoot in scripts to simplify this to:

# PowerShell v3 or higher

#requires -Version 3.0
Import-Module $PSScriptRoot\..\MasterScript\Script.ps1

Answer 3

The new Method for this is $PSScriptRoot

Import-Module $PSScriptRoot\Script1.ps1

Nice little one liner.
