how to output debugging messages from install.ps1 in NuGet

Question

I am developing a NuGet package, including an install.ps1 script which runs during the package installation. I would like to be able to output messages from my script and also output the results of running .bat files from within my sript.

Here is my install.ps1:

param($installPath, $toolsPath, $package, $project)
Write-Output "Running install.ps1 for MyPkg"
Set-Location $toolsPath
.\helper.bat | Write-Output

When I install my package in Visual Studio, then I look in the Package Manager option in the Output page, I see:

Executing script file 'C:\Test\packages\MyPkg.1\tools\install.ps1'.

and it seems the script is working (I can tell in other ways that helper.bat ran), but I don't see any of the output. How can I get the output working?

Answer 1

I could not get the output when installing from the NuGet Package Manager Dialog, I'll dig a bit later to see where it's going.

But you should be able to see it when installing from the Nuget console (Tools->Library Package Manager->Package Manager Console). The output went directly in the console. Example :

PM> uninstall-package samplepackage
hello from unninstal.ps1
Successfully removed 'samplepackage 1.0.0' from WebApplication24.

unninstal.ps1 :

param($installPath, $toolsPath, $package, $project)
Write-Host "hello from unninstal.ps1"
