Dotnet 还原为 NuGet package 提供 301 错误

Question

我的代码昨晚运行良好，但是当我今天尝试使用dotnet restore恢复它时，出现以下错误。

我正在使用 Ubuntu 20.04，我的 dotnet 配置如下

.NET Core SDK (reflecting any global.json):

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

但是，如果我尝试直接访问这些 URL，我可以访问它们吗？ 我也在使用VPN。 会不会是因为这个？

Answer 1

我已经设法解决了这样的问题：

1- 从这里下载 Nuget.exe

2-将Nuget.exe添加到windows路径（可以复制到c:/windows/system32）

3-打开命令行并导航到您的解决方案文件夹并运行以下命令：

nuget.exe 恢复-DisableParallel

希望它有效。
