linux - 在 Windows 上的 bash 上运行 Kestrel

Question

我正在尝试在 Windows 上的 bash 上运行一个简单的网站(Windows 周年更新 bash)，但到目前为止我一直没有成功。

我能够创建和运行控制台应用程序，但每当我输入

dotnet run 

在一个网络项目中，我得到:

    Unhandled Exception: System.AggregateException: One or more errors occurred. (Error -98 EADDRINUSE address already in use) ---> Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -98 EADDRINUSE address already in use

   at Microsoft.AspNetCore.Hosting.WebHostExtensions.Run(IWebHost host)
   at WebApplication.Program.Main(String[] args)

有人成功过吗？我是不是对“精简的 Linux 测试版”要求太多了？

编辑:

要重现该行为，请在 bash on windows 提示符下键入:

mkdir mytestwebsite
cd mytestwebsite
dotnet new -t web
dotnet restore
dotnet run

然后问题就出现了。

该错误消息的重要部分是:

Error -98 EADDRINUSE address already in use

这表示某些东西已经绑定(bind)到您尝试监听的端口。例如，如果您尝试运行 Kestrel 并在端口 80(默认 HTTP 端口)上监听，那么 Apache 也可能已经连接。您要么需要关闭已经在该端口上监听的任何内容，要么更改您的应用程序以选择一个新端口。
