Question

我从https://www.github.com/aspnet/home中检索示例代码。当我恢复最新/ HelloMvc文件夹中的包时，发生以下错误：

Warning: FindPackagesById: Microsoft.AspNet.Http.Features
  HTTP request timed out. Retrying.

但我成功恢复'lastest / ConsoleApp'，然后我使用wget下载带有失败网址的pacakge，没有问题，我可以从该软件包中解压dll。

我已恢复'lastest / HelloMvc'使用mono 1.0.0-beta7-12274运行时，或恢复'1.0.0-beta5 / HellowMvc'使用1.0.0-beta5运行时，或更改为使用dockerfile（ microsoft / aspnet），即使更换电脑，错误也是一样的〜

Answer 1

你试图运行mozroots --import --sync吗？我在https://github.com/aspnet/Docs/issues/184找到了解决方案并且对我有用。

Answer 2

使用以下命令 env MONO_THREADS_PER_CPU = 2000 dnu restore 。这对我有用。您还可以设置全局环境变量，在这种情况下，每次执行 dnu restore 时都不必键入 env MONO_THREADS_PER_CPU 。

恢复vnext mvc演示时，dnu总是被取消或超时
