Build.ps1 fails downloading PowerShell package

[nbarnwell]

1. Forked repo
2. Executed build.ps1

Expected Build to run

Actual Build failed with following error:

Install-PSResource: C:\Code\Github\dotnet-adr\build.ps1:90

I noticed an additional warning:

WARNING: The cmdlet 'Install-Module' is deprecated, please use 'Install-PSResource'.

Is it worth moving to PSResourceGet?

Hi @nbarnwell, thanks for opening this issue - please can you share the output you get from $PSVersionTable?

HTH:

Thanks for that @nbarnwell. It's a bit of puzzle, we normally see these types of issues when the script is run in a Windows PowerShell terminal (where we've forgotten to set a #requires directive), but the output above suggests otherwise.

What happens if you try to manually install the module?

Install-Module InvokeBuild -RequiredVersion 5.10.3 -Scope CurrentUser -Force -Repository PSGallery

If the above works, then I'd suggest adding the following to build.ps1 before running it again, to disable some functionality we use in our repo/org that might not work for you (anywhere before the task . FullBuild line should be fine):

$SkipPrAutoflowEnrollmentCheck = $true

[nbarnwell]

That didn't work, and gave the same error. I'm convinced it's because of the tyre-fire that is PowerShellGet/CompatPowerShellGet/PSResourceGet at the moment.

[nbarnwell]

Further to my previous comment, I tried it on Windows PowerShell as opposed to PowerShell (i.e. the .NET Core-based one) and that install worked. However, the build.ps1 didn't, because there's some newer syntax involved there:

PS C:\Code\Github\dotnet-adr> .\build.ps1

+                                                 ~

[JamesDawson]

Thanks for that @nbarnwell. Yes, the build does require PowerShell Core, so that's expected at least!

tyre-fire that is PowerShellGet/CompatPowerShellGet/PSResourceGet

Could be :-) Although I thought the real 'fun' was going to start in the next version when they enable the compat layer and switch things over.

I'll do an experiment to change the build script over to using PSResourceGet, but in the meantime would you mind sharing your output from the following?

Get-Module -ListAvailable Microsoft.PowerShell.PSResourceGet
Get-Module -ListAvailable PowerShellGet

Also, in a fresh PowerShell session, please can you share the output from running the following immediately after build.ps1 (and it failing)?

Get-Module

[nbarnwell]

real 'fun' was going to start in the next version when they enable the compat layer and switch things over.

They've done that now, I think - see https://devblogs.microsoft.com/powershell/powershellget-in-powershell-7-4-updates/. They repurposed the name "PowerShellGet" to mean the compatibility layer between the old package management and the new PSResourceGet cmdlets. It used to be called "CompatPowerShellGet".

I do a lot of PowerShell module stuff with an authenticated AzDO artifacts feed, so it's unsurprising I get a lot of results for the following. I expect the source of my problem is in here somewhere:

Thanks for all that @nbarnwell. I've opened a draft PR which switches the build script over to using PSResourceGet - it'll be interesting to see how it runs in your environment?

My reading of that blog post, was that the compat layer wasn't getting switched-on by default until PS 7.5? It seems like your environment has already got those bits installed, so I'll do some testing this end to see if I can at least repro the issue after having installed those beta bits.

I think the challenge will be how/if we can put guardrails in without bloating the script with more 'module installation' boilerplate. For sure a sign of 'fun times' ahead!
