NuGet参考存储在哪里？

标签： c# nuget

我无法this C# solution (click to download - 666MB或browse on GitHub here）进行编译：

我得到的错误是

  

此项目引用了此计算机上缺少的NuGet软件包。使用NuGet软件包还原下载它们。有关更多信息，请参见http://go.microsoft.com/fwlink/?LinkID=322105。丢失的文件是.. \ packages \ Accord.3.8.0 \ build \ Accord.targets。 bootcamp_basecamera C：\ Users \ MyUser \ Desktop \ ComputerVision_Bootcamp-master \ bootcamp_basecamera \ bootcamp_basecamera \ bootcamp_basecamera.csproj 144

boot_camp_basecamera.csproj中有问题的行是：

<Error Condition="!Exists('..\packages\Accord.3.8.0\build\Accord.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Accord.3.8.0\build\Accord.targets'))" />

我在StackOverflow上经历了每一个NuGet问题/解决方案，但是没有一个答案对我有用。

我尝试了软件包还原，我手动卸载了所有NuGet软件包，然后再次安装它们。

这并没有使错误消息消失。

因此，我想问这个错误消息的确切来源。 它说：“该项目引用了……”。 我什至删除了package.config文件，仍然看到此错误。

因此，我想问这个引用的确切存储位置，因为它不能是packages.config（因为我删除了它们）。

谢谢。

根据请求，以下是相关的.csproj文件的内容：

2 个答案:

答案 0 :(得分：6)

问题在于目录结构是

  • bootcamp_complete.sln
  • bootcamp_basecamera /
    • bootcamp_basecamera.sln
    • bootcamp_basecamera /
      • bootcamp_basecamera.csproj

即.csproj的深度为两个级别，并且有两个.slns。 .csproj中的HintPaths仅为..\package，即它们是为bootcamp_basecamera.sln（而不是bootcamp_complete.sln）还原的软件包设置的。

所以我认为您的选择是

  1. 打开每个子项目自己的.sln并在其中恢复包-已下载文件的复制很多，但是如果您只需要单独使用它们并且它们彼此不依赖，则这可能会更容易
  2. 修改.csprojs以将提示路径设置为..\..\package而不是..\package
  3. 更改文件夹结构：使用其自己的.sln文件删除中间文件夹，因此bootcamp_basecamera.csproj距根目录只有一个文件夹深度，然后更新顶级.sln以更改路径

答案 1 :(得分：1)

有一些方法可以安装缺少的软件包

  • 您可以删除解决方案目录下“ packages”文件夹中的所有文件，然后 您可以通过右键单击解决方案再次安装所有nuget软件包 名称，然后单击“还原Nuget软件包”项

  • 您只需运行Update-Package –reinstall
