I'm getting this error when I try to run the following line:
Install-Package UmbracoCms
And I'm getting this error:
Install-Package : An error occurred while downloading package 'Newtonsoft.Json.10.0.2 : ' from source 'https://www.nuget.org/api/v2/'
I have tried to do the following:
Install-Package Newtonsoft.Json -Version 10.0.2
And I still got this error:
Package 'Newtonsoft.Json.10.0.2 : ' does not exist in project 'Umbraco_MVC'
I also tried to delete the line with Newtonsoft in packages.config, but there is no line with that reference there
If I'm reading this correctly, and you're having an issue with getting JSON.NET installed through NuGet through both methods, then this (loosely related) GitHub issue thread might be of use to you.
https://github.com/google/google-api-dotnet-client/issues/1041
It involves changing the NuGet API URL you use to a newer version.
If your installation IS working, but you're still getting an issue, check your website bin folder to see if the dll is there. If not, check the References section of your web project to see if the dll is being referenced by your project.

In my build pipeline, I have the following step:
I am getting the following error:
##[error]The nuget command failed with exit code(1) and error(NU1102: Unable to find package Microsoft.Windows.SDK.BuildTools with version (>= 10.0.19041.8)
When I go to the NuGet page for this package: Microsoft.Windows.SDK.BuildTools, I see that it only has one version: 10.0.18362.3-preview. I am not sure why the NuGet restore step is trying to get a higher version that does not exist. Why is this happening and how can I fix it? Note: this is my first Pipeline.
Agent Specification: Windows-2019.
From this page, you can see only two versions of the package Microsoft.Windows.SDK.BuildTools are listed:
10.0.19041.1
10.0.18362.3-preview
When open the page of version 10.0.19041.1, you can see the warning message to notify that this package version has been deprecated. But it seems that you can still download and install it.
I think the other package versions may have been permanently deleted by the owner due to some security vulnerabilities. So you no longer find them.
You can try to open your project using Visual Studio on your local machine, and change to use version 10.0.18362.3-preview in your program.

I have been migrating my project to Visual Studio 2015 RC. I have also refactored it into separate projects. Now I need to add a migration for a model change in entity framework but as soon as I open the Package Manager Console I get this error message:
Set-DefaultScaffolder : Cannot get an instance of EnvDTE.DTE At C:\Users...\Visual Studio 2010\Projects\MyProject\packages\T4Scaffolding.Core.1.0.0\tools\init.ps1:50 char:30
If I clear the console and try again, I get "an exception has been encountered" - with more information in the activity log. Inspect the activity log and the exception is:
System.ArgumentOutOfRangeException: Specified argument was out of the
range of valid values. Parameter name: span at
Microsoft.VisualStudio.Text.SnapshotSpan..ctor(ITextSnapshot snapshot,
Span span) at
NuGetConsole.Implementation.Console.WpfConsoleClassifier.GetClassificationSpans(SnapshotSpan
span) at
Microsoft.VisualStudio.Text.Classification.Implementation.ClassifierTagger.d__1.MoveNext()
at
Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator`1.d__1.MoveNext()
I realised that I had removed some packages that I probably should not have. So I re-installed these:
ModelScaffolding 0.9.2
MvcScaffolding 1.0.9
T4Scaffolding 1.0.8
This appears to have taken the second exception (ArgumentOutOfRangeException) away. However, now when I try Add-Migration I get
Join-Path : Cannot bind argument to parameter 'Path' because it is
null. At C:\Users...\Visual Studio
2010\Projects\MyProject\packages\EntityFramework.6.1.0\tools\EntityFramework.psm1:713
char:27
I tried uninstalling and re-installing Entity Framework. I noticed during install that the Join-Path error was displayed again, but package-manager continued, and reported a successful install. I still got the error when I tried Add-Migration
Then I opened the solution in Visual Studio Express 2013. I still get the initial Cannot get an instance of EnvDTE.DTE error, but I can clear the console window and I can add a migration - Phew!
I'd still like to get rid of that error message...and use VS 2015...
There was an error in the NuGet VS extension. You can fix this by installing the latest NuGet (not available through VS yet). This may require an update of Powershell and/or Windows Management Framework.
Following the tutorial for mvvmcross here: http://www.youtube.com/watch?v=_DHDMNB_IeY&list=PLR6WI6W1JdeYSXLbm58jwAKYT7RQR31-W&index=1
I've set up my PCL xml files to include MonoTouch and Mono for Android as instructed here: http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html
If I try to use nuget I get an error that an item with the same key has already been added:
I can add other project types to the solution and NuGet works fine, it's something specific to PCL projects. Here is the console output:

My guess is that one of the XML files you added git snafu'd during copy and paste.
Try deleting whatever you added and try adding them again.
Alternatively, it could be that someone else has added conflicting files? Eg xamarin have recently added pcl support so maybe they've added files?
To try collecting more info, you could try using the nuget command line - does that give you any more diagnostic info.
