powershell - Dot sourcing a file doesn't work -

im following this question can't seem working.

(for sake of testing) have powershell module 2 scripts: variables.ps1 , function.ps1 , manifest mymodule.psd1 (these files in same directory)

this content of variables.ps1:

$a = 1; $b = 2; 

this content of function.ps1

. .\variables.ps1 function myfunction {     write-host $a     write-host $b } 

when import module , call myfunction. output:

c:\> import-module .\mymodule.psd1 c:\> myfunction . : term '.\variables.ps1' not recognized name of cmdlet, function, script file, or operable program. check spelling of name, or if path included, verify path correct , try again. @ c:\users\jake\mymodule\function.ps.ps1:8 char:4 +     . .\variables.ps1 +       ~~~~~~~~~~~~~~~~~~~~~     + categoryinfo          : objectnotfound: (.\variables.ps1:string) [], parentcontainserrorrecordexception     + fullyqualifiederrorid : commandnotfoundexception 

why doesn't work?

when use relative paths in scripts, they're relative callers $pwd - current directory you're in.

to make relative directory current script located on file system, can use automatic variable $psscriptroot

. (join-path $psscriptroot variables.ps1) 

the $psscriptroot variable introduced in powershell version 3.0, powershell 2.0 can emulate with:

if(-not (get-variable -name 'psscriptroot' -scope 'script')) {     $script:psscriptroot = split-path -path $myinvocation.mycommand.definition -parent } . (join-path $psscriptroot variables.ps1)
