.net core 尝试安装dotnet工具时出错

我正在尝试安装Microsoft.dotnet-interactive tool，但遇到此问题

也试过用不同的工具解决同一问题

我尝试了以下命令

dotnet工具安装--全局Microsoft.dotnet交互式
dotnet工具安装--全局Microsoft.dotnet-interactive--版本1.0.110520
dotnet工具安装--全局Microsoft.dotnet-interactive--版本1.0.115407
dotnet工具安装--全局dotnet交互
dotnet工具安装--全局dotnet交互--版本1.0.115407

网络信息

有什么想法吗

非常感谢您，您没有运行最新的.NET Core SDK版本（或运行时）：如果您能够在特定的计算机上运行，请安装最新版本（取决于您的Visual Studio版本）。这可能会解决你的问题

我通过

dotnet--info

进行配置，因为这些工具在Visual Studio 2019上安装正确。如果您已经更新了.NET内核，那么另一个主要区别是Windows版本；不确定这是否重要：

使用最新的.NET Core SDK更新，相同问题，感谢您尝试。您是否在本地用户文件夹下看到.dotnet\tools\.store文件夹？安装交互式工具时会修改此选项。@moxede3067我已将我的版本信息添加到我的答案中。是的，我有相同的版本3.1.201，是的，我有C:\Users*\.dotnet\tools\.store\.stage文件夹。dotnet\tools\.store文件夹中有文件吗？结构在我的机器上，但没有文件。我删除了这些文件夹，然后安装了dotnet交互工具，并通过成功安装重新创建了这些文件夹。已使用最新的.NET Core SDK更新，问题相同，感谢尝试。您是否在本地用户文件夹下看到.dotnet\tools\.store文件夹？安装交互式工具时会修改此选项。@moxede3067我已将我的版本信息添加到我的答案中。是的，我有相同的版本3.1.201，是的，我有C:\Users*\.dotnet\tools\.store\.stage文件夹。dotnet\tools\.store文件夹中有文件吗？结构在我的机器上，但没有文件。我删除了这些文件夹，然后安装了dotnet交互工具，并在成功安装后重新创建了这些文件夹。
