我有一个ASP.NET MVC5应用程序，它昨天运行，现在我在尝试构建时遇到以下错误：

此项目引用此计算机上缺少的NuGet包

我选中了两个选项，这两个选项允许nuget自动下载并安装丢失的软件包。我还尝试删除packages文件夹中的所有文件，然后让nuget重新下载它们。另外，当我打开nuget并查找更新时，它会说不需要安装任何更新。我不知道还能做些什么来超越这个令人惊讶的恼人问题

我还通过右键单击项目并选择该选项启用了nuget restore。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。我已尝试重新构建，但仍然出现相同的错误。

是否可能已将包还原到错误的文件夹？检查csproj文件中的路径是否正确

如果它们不同，则可能是由于现在正在将包还原到不同的位置。这可能是由于签入NuGet.Config文件时指定了如下节点造成的：

<add key="repositoryPath" value="..\..\Packages" />

程序包正在恢复，但项目仍在查看旧位置。

在我的情况下，我必须从.csproj文件中删除以下内容：

<Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.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('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
</Target>


此项目引用此计算机上缺少的NuGet包。启用NuGet软件包还原以下载它们。有关详细信息，请参阅http://go.microsoft.com/fwlink/?LinkID=322105. 缺少的文件是{0}。

事实上，在这个片段中，您可以看到错误消息的来源

我正在从MSBuild集成包还原转换为自动包还原（

我遇到了同样的问题。在我的例子中，安装Microsoft.Bcl.Build软件包修复了这个问题。

我在MVC web应用程序中引用类库时也遇到了同样的问题

问题是两个项目之间的nuget包版本号不匹配

例：我的类库的log4net为1.2.3，但我的webapp为1.2.6

修复方法：只需确保两个项目引用的版本号相同。

在我的情况下，它与Microsoft.Build.Bcl版本有关。我的nuget包版本是1.0.21，但我的项目文件仍然指向1.0.14版本

因此，我将.csproj文件更改为：

  <Import Project="..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />
   <Target Name="EnsureBclBuildImported" BeforeTargets="BeforeBuild" Condition="'$(BclBuildImported)' == ''">
    <Error Condition="!Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="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=317567." HelpKeyword="BCLBUILD2001" />
    <Error Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="The build restored NuGet packages.

  </Target>

致：

构建再次工作。

以下是我用来解决问题的步骤：

要将nuget软件包添加到解决方案中，请执行以下操作：

右键单击要引用nuget的项目（不是解决方案）包裹

选择：管理nuget包

在弹出窗口的左侧，您有三个选择。如果选择“联机”>“Microsoft&.NET”，则可以安装 Microsoft ASP.NET Web API 2.2软件包grouper（或任何软件包你需要——我的就是这个）

现在右键单击您的解决方案（不是项目）并选择启用nuget包还原。这将导致在编译时自动下载包

在我的例子中，它发生在我将我的解决方案文件夹从一个位置移动到另一个位置，重新组织它一点，在这个过程中，它的相对文件夹结构发生了变化

因此，我必须在我的

.csproj

文件中编辑与以下内容类似的所有条目

  <Import Project="..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />

到

（请注意从。\packages\
到packages\
的更改。在您的情况下，它可能是一种不同的相对结构，但您明白了。）

我可以通过右键单击我的解决方案，然后单击启用NuGet Package Restore选项轻松解决此问题

（注意：确保已从工具-->扩展和更新-->Visual Studio 2013的Nuget软件包管理器安装Nuget。如果没有，请先安装此扩展）

希望有帮助。

我在解决方案根文件夹中创建了一个名为“.nuget”的文件夹然后在此文件夹中添加了文件“NuGet.Config”，其中包含以下内容

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<solution>
 <add key="disableSourceControlIntegration" value="true" />
</solution>
</configuration>

然后创建文件“.nuGet.targets”，如下所示 $（MSBuildProjectDirectory）\


假的

$（[System.IO.Path]：：合并（$（SolutionDir），“.nuget”））
$（[System.IO.Path]：：合并（$（ProjectDir），“packages.config”））
$（[System.IO.Path]：：合并（$（SolutionDir），“包”））
$（SolutionDir）.nuget
packages.config
$（SolutionDir）包
$（NuGetToolsPath）\nuget.exe
@（PackageSource）
“$（NuGetExePath）”
mono——运行时=v4.0.30319$（NuGetExePath）
$（TargetDir.Trim（'\\'））
-请求发送
$（NuGetCommand）安装“$（PackageConfig）”-源“$（PackageSources）”$（RequiredSentSwitch）-o“$（PackagesDir）”
$（NuGetCommand）包“$（项目路径）”-p配置=$（配置）-o“$（PackageOutputDir）”-符号
恢复性包装；
$（BuildDependsOn）；
$（BuildDependsOn）；
构建包；

编辑.sln和.csproj并不总是那么容易或令人满意。获得错误列表后，您可以看到哪些项目缺少包（此外，“引用”节点通常指示缺少程序集，除非包是源代码、资源、图像或仅基于文本的包）

删除然后添加包不是一个简单的过程
