iis - 无法加载应用程序或执行命令 'Microsoft.AspNet.Server.Kestrel'

Question

我正在尝试将我的 ASP.NET 5 WebApi 部署到远程服务器(Windows Server 2008 R2)，但无法使用 IIS 正确运行它。

项目.json

{
  "webroot": "wwwroot",
  "version": "1.0.0-*",

  "dependencies": {
    "App.Data": "1.0.0-*",
    "App.Model": "1.0.0-*",
    "App.Repository": "1.0.0-*",
    "App.ViewModel": "1.0.0-*",
    "AutoMapper": "4.1.1",
    "Microsoft.AspNet.Authentication": "1.0.0-rc2-16009",
    "Microsoft.AspNet.Authentication.JwtBearer": "1.0.0-rc2-16009",
    "Microsoft.AspNet.Diagnostics": "1.0.0-rc2-16136",
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc2-15873",
    "Microsoft.AspNet.Mvc": "6.0.0-rc2-16377",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc2-16017",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-rc2-15932",
    "Microsoft.AspNet.StaticFiles": "1.0.0-rc2-15916",
    "Microsoft.Framework.Configuration.Json": "1.0.0-rc1-15666",
    "Microsoft.Framework.Logging": "1.0.0-rc1-15644",
    "Microsoft.Framework.Logging.Console": "1.0.0-rc1-15644",
    "Microsoft.IdentityModel.Protocols.OpenIdConnect": "2.0.0-rc1-211120828"
  },

  "commands": {
    "kestrel": "Microsoft.AspNet.Server.Kestrel",
    "web": "Microsoft.AspNet.Server.Kestrel"
  },

  "frameworks": {
    "dnx451": { }
  },

  "exclude": [
    "wwwroot",
    "node_modules"
  ],
  "publishExclude": [
    "**.user",
    "**.vspscc"
  ]
}

当我尝试从浏览器访问应用程序时，我没有收到任何响应。当我执行 web.cmd 时在服务器上，我收到以下错误:

Error: Unable to load application or execute command 'Microsoft.AspNet.Server.Ke
strel'. Available commands: kestrel, web.
System.IO.FileNotFoundException: Le fichier spécifié est introuvable. (Exception

确保在目标服务器上安装了所有依赖项。运行 dnu list在 cmd 中查看所有项目依赖项。

如果其中一些未安装(它们将显示为红色)运行 dnu restore恢复所有包。

您还可以通过运行 dnu build 来确保您的项目成功构建。

希望能帮助到你..
