C# 从源代码生成Microsoft.AspNet.Identity，解析包时引发错误

我正试图从中可用的源代码建立一个网络身份。它在构建过程中抛出错误。复制步骤：

启动Visual Studio 2019社区并选择克隆存储库。输入以下URL并单击克隆：

将nuget.exe复制到克隆项目中的

.nuget

以下包含

\\

部分的目录路径似乎有问题，但我不知道为什么它包含在路径中：

C:\Users\MyUserName\Source\Repos\AspNetIdentity\ \packages\Moq.4.0.10827

从源代码生成Microsoft.AspNet.Identity，在 解析包

该问题位于

numget.targets

文件的

restorecomand

下

和默认情况下，

SolutionDir

属性包含

\

。在命令中，它将使MSBuild无法找到包地址

除此之外，我注意到：

-solutionDir“$（solutionDir）”

SolutionDir

和

“

之间有一个空格，您应该删除它

解决方案

更改为在

nuget.targets

文件中使用此选项：

<SolutionDir1>$(SolutionDir.Trim('\'))</SolutionDir1>

<RestoreCommand>$(NuGetCommand) install "$(PackagesConfig)" -source "$(PackageSources)"  $(RequireConsentSwitch) -solutionDir "$(SolutionDir1)"</RestoreCommand>

$（SolutionDir.Trim（'\'））
$（NuGetCommand）安装“$（PackageConfig）”-源“$（PackageSources）”$（RequiredSentSwitch）-solutionDir“$（SolutionDir1）”

完成后，应关闭VS，然后重新启动项目以重新加载新的csproj文件以启用更改

---

注意：使用一个新属性

SolutionDir1

，该属性将删除该

\

，然后在命令中使用它。

问题来自

nuget.targets

文件的

RestoreCommand

。默认情况下，

solutiondir

属性包含\。在命令中，它将使MSBuild无法找到程序包地址。因此您应该删除该\。我将添加一个答案以帮助您解决此问题。
