我试图构建一个ASP.NET Core 6 Razor页面应用程序，但只连接到我们的内部nuget包存储，而不是nuget.org。nuget恢复抛出错误，因为它找不到.NET Core Framework库，如System.IO和System.Linq。
我的同事能够在不连接到www.example.com的情况下构建这个应用程序nuget.org，它构建在我们的Azure DevOps构建服务器上，但它在本地失败了，出现了122个错误，如下所示。
NU 1101-找不到包System.IO
NU 1101-找不到软件包System.Linq
我安装了.NET Core 6 SDK和运行时

我试过删除项目并将其从源代码管理中拉下来。我试过清理项目文件。我试过卸载并重新安装.NET Core和Visual Studio。
有人知道为什么nuget找不到我的本地sdk库吗？我该如何解决这个问题？
