无法在 windows server 2012 r2 中加载 libuv？

Question

在 Visual Studio 代码中，我在命令行面板中发出 dnx kestrel。 但是我遇到了这样的错误

我该如何解决这个问题？ 谢谢。

Answer 1

Kestrel 使用 libuv 一个异步 I/O 库。因此，您可以安装它以使用 Kestrel 作为 Web 服务器，或者您可以使用 dnx web 来启动您的应用程序，其中 web 是 project.json 中的一个命令。

"commands": {
"kestrel": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.Kestrel --config hosting.ini",
"web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --config hosting.ini"}

为什么要在win2012上使用红隼？您最好改用 IIS 或 AspNet selfhost。 Kestrel 应该在 Linux 或 Mac 上使用

哦，所以有一种叫做自托管的东西？感谢@agua from mars 提供的信息
