此项目引用此计算机上缺少的 NuGet 包 [英] This project references NuGet package(s) that are missing on this computer

问题描述

我有一个昨天运行的 ASP.NET MVC5 应用程序，现在我在尝试构建时遇到此错误:

I have an ASP.NET MVC5 application that worked yesterday and now I am getting this error when I try to build:

此项目引用了此计算机上缺少的 NuGet 包.

This project references NuGet package(s) that are missing on this computer.

我选中了两个选项，允许 nuget 自动下载和安装丢失的软件包.我还尝试删除包文件夹中的所有文件，然后让 nuget 重新下载它们.此外，当我打开 nuget 并查找更新时，它说不需要安装任何更新.我不知道还能做些什么来解决这个令人惊讶的恼人问题.

I have the two options checked that allow nuget to automatically download and install missing packages checked / turned ON. I have also tried deleting all of the files in the packages folder and then have nuget re-download them. Also when I open nuget and look for updates it says there are none that need to be installed. I can't figure what else to do to move beyond this amazingly annoying issue.

我还通过右键单击项目并选择该选项来启用 nuget 恢复.然后它添加了一个 nuget 文件夹和该文件夹中的三个项目，但没有解决问题.我已经尝试重新构建，但仍然出现相同的错误.

I have also enabled nuget restore by right clicking the project and selecting that option. It then added a nuget folder and three items in that folder and does nothing to resolve the problem. I've tried re-building and still get the same error.

推荐答案

就我而言，我不得不从 .csproj 文件中删除以下内容:

In my case, I had to remove the following from the .csproj file:

<Import Project="$(SolutionDir).nugetNuGet.targets" Condition="Exists('$(SolutionDir).nugetNuGet.targets')" />
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
  <PropertyGroup>
    <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
  </PropertyGroup>
  <Error Condition="!Exists('$(SolutionDir).nugetNuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir).nugetNuGet.targets'))" />
</Target>

事实上，在这个片段中，您可以看到错误消息的来源.

In fact, in this snippet you can see where the error message is coming from.

我正在从 MSBuild-Integrated Package Restore 转换为 Automatic Package Restore (http://docs.nuget.org/docs/workflows/migrating-to-automatic-package-restore)
