How do I use constants in a PowerShell module?
1
I want to declare some variables as global constants in a module (web service response codes). The problem is, when I import the module (more than once, either with or without -Force) I get
Import-Module : Cannot remove variable ADDED_INCLUSION_STATUS because it is
constant or read-only. If the variable is read-only, try the operation
again specifying the Force option.
What workaround/approach can I use?
My declaration looks like this:
Set-Variable -name STATUS_ABORTED -value 0 -Scope Global -option Constant
powershell variables module

Did you flag them asConstantorRead-Only? As the error message says,Read-Onlyvariables can be forcibly removed (though, I'm not sure PowerShell will do this for you behind the scenes). Alternatively, does it help if youRemove-Modulebefore re-importing?

I like this question and it is not lacking code, as your text describes anything one needs to know to reproduce. However I would really love to see an Minimal, Complete, and Verifiable example which attracts more users to test your case and to troubleshoot your problem

I think you should change your declaration to:
Set-Variable -name STATUS_ABORTED -value 0 -Scope Global -Option ReadOnly -Force -ErrorAction SilentlyContinue
A ReadOnly variable can be redefined by using the -Force switch. A Constant is there for the duration of the session. These cannot be changed or removed without closing PowerShell.
