Nuget似乎在Visual Studio 2017中不起作用（仅.net Core）

Question

我安装了最新版本的.NET Core，最新版本的Visual Studio 2017和最新版本的NuGet。 当我创建一个全新的ASP.NET Core Web应用程序（MVC）时，该项目似乎没有创建一个有效的项目。 Dependencies项目有一个警告标签，当我单击它时，我看到带有警告标签的NuGet，然后在它下面是带有警告符号的Microsfot.AspNetCore.All。

当我尝试执行NuGet还原时，它告诉我“操作失败，因为无法加载项目WebApplicaction4的详细信息。” 如果在解决方案资源管理器中单击Microsoft.AspNetCore.All条目，VS 2017崩溃。

当我运行.NET Framework（仅Core）时，我没有这个问题。

编辑：

-我正在运行.NET Core 2.1.2

-当我运行dotnet new mvc --name WebApplication6然后运行nuget restore一切都可以正常运行，但是当我在VS中打开该应用程序时，将得到与下图相同的错误显示

这是通过Visual Studio的GUI创建的应用程序的命令行错误消息：

Answer 1

MSbuild和NuGet在项目路径中的某些字符可能有问题。

将项目移出包含单引号'字符的目录层次结构。
