Visual Studio 2012中的NuGet构建失败

Question

I've got NuGet 2.1.31002.9028 installed in Visual studio 2012. When I enable package restore and add any package (like EntityFramework) to my project, I get the following error when building the project:

Error   1   The system cannot find the path specified.  ConsoleApplication1
Error   2   The command ""D:\Code\ConsoleApplication1\.nuget\nuget.exe" install "D:\Code\ConsoleApplication1\ConsoleApplication1\packages.config" -source ""  -RequireConsent -solutionDir "D:\Code\ConsoleApplication1\ "" exited with code -1.    ConsoleApplication1
Warning 3   The referenced component 'System' could not be found.   ConsoleApplication1

There's a warning like the one above for every reference. The command in the second error works fine when I run it from a command prompt. I have "Allow NuGet to download missing packages during build" checked and I also tried adding a EnableNuGetPackageRestore environment variable, none of which fixed the problem. I also don't get this problem on my other machine, which makes it even more confusing.

I appreciate any help on this, and am more than happy to provide any additional info if needed.

Answer 1

You should try to allow NuGet to download missing packages during build :

I had the same issue, so it should help.

Answer 2

This is a tough one, here are few things I would have tried

1. Create a console app and see if it repros? (without nuget package installation)
2. Is system correctly referenced in references? May be try removing and adding it back.
3. Does it repro for other project types, like class library?

Hope it helps.
