@alexandair where is the location of module repositories?

~\Desktop> Get-PSRepository

@SteveL-MSFT Do you know where is the module repositories?
What Get-PSRepository for? like NuGet?

[SteveL-MSFT]

@chucklu I don't know why you aren't showing any repositories, but you can do Register-PSRepository -Default to get PowerShell gallery back

[chucklu]

Hi @SteveL-MSFT ,
After Register-PSRepository -Default still the same error.
Where is the source code of Register-PSRepository function? I want to check the source code.

~\Desktop> Register-PSRepository -Default
~\Desktop> Get-PSRepository

@chucklu see https://github.com/PowerShell/PowerShellGet/blob/37f2a3f477213be79104695235c8b3ab5eae6e38/PowerShellGet/public/psgetfunctions/Register-PSRepository.ps1

[SteveL-MSFT]

@chucklu this appears to be an issue with PowerShellGet. I would suggest opening an issue there to continue this discussion. Closing this issue in this repo.

[chucklu]

@SteveL-MSFT I have checked the parameters for the Register-PSRepositor, I have a default proxy on my computer, so it could be the proxy problem.
I will open a new issue on PowerShellGet repository.

Hi @SteveL-MSFT , @alexandair
I have register the ps repository successfully.

~\source\repos\GitHub\Other\PowerShellGet [development ≡]> Get-PSRepository

However, when I try to install this module , still failed

After check the parameters of the Install-Module , it still need the proxy parameter.

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its InstallationPolicy value by running the Set-PSRepository cmdlet. Are you sure you want to install the modules from 'PSGallery'?

It works now

[SteveL-MSFT]

@chucklu glad you solved it! Seems like a better error message should have been given if it can't connect to the gallery due to proxy
