dnu restore fails with error: FileNotFoundException

[rupreetg]

I wanted to try out sample project to understand coreCLR better and learn abour DNX family.

I tried this link https://github.com/dotnet/coreclr/blob/master/Documentation/get-dotnetcore-dnx-windows.md to get started and followed everything as mentioned on my windows machine (8.1, x64)

When I run "dnu restore", I get the following error -

Restoring packages for D:\work\labs\coreCLR\firstAppUsingCoreclr\project.json

GET https://www.nuget.org/api/v2/FindPackagesById()?id='System.Console'.

Restore failed

The local package source D:\Work\Grapine\Products\ErrorTracking\raygun4net-master\packages doesn't exist

Note here - my project.json looks exactly same as mentioned in the github link but its trying to find packages in one of my existing project which doesn't have any relation to it.

I've tried searching on this but haven't found so posting it here.

Here are some more info -

"dnu list" gives this output -

Check if you have any additional package sources defined in %APPDATA%\NuGet\NuGet.Config.

[rupreetg]

Yup, it has additional packages -

<add key="Package source" value="C:\Users\rupreetg\Downloads\Xamarin.QuickUI.1.0.6041.nupkg(1)" />
<add key="Raygun" value="D:\Work\Grapine\Products\ErrorTracking\raygun4net-master\packages" />
<add key="SoiChat" value="D:\Work\SioChat\Soichat.App-master\packages" />

But I am still confused as to why its failing?

[akoeplinger]

Presumably because that local package folder isn't what dnu expects (does it contain actual nupkgs?).

[rupreetg]

I am assuming the actual packages have moved or not placed in that folder any more hence it fails. I agree that dnu is expecting the packages to be there but it seems it shouldn't fail if any existing package doesn't exist in nuget config, especially if that package isn't part of the program I trying to compile. Not sure if this is by design or a bug.

[akoeplinger]

dnu/nuget doesn't know that the package source doesn't contain relevant packages, it just tries every package source until it finds the packages in one of them.

It looks like restore failing on a non-existing local package source was a deliberate change introduced in aspnet/dnx#1032. Just remove the package source from NuGet.config or use the --ignore-failed-sources flag ;)

[rupreetg]

Yup, i was able to move ahead post removing the non-existent packages! Thanks for your help!

The PR link you gave was helpful in understanding the behavior and why it was done this way, so 👍
