无法使用命令行'dotnet.\ myapi.dll'启动进程，ErrorCode ='0x80004005:80008096 [英] failed to start process with commandline 'dotnet .\myapi.dll', ErrorCode = '0x80004005 : 80008096

问题描述

我在此处问了一个问题关于如何确保构建中包含正确版本的dotnet.

I asked a question here on how to ensure the correct version of dotnet is included in the build.

我想知道该版本是否仍未部署. 我要在已部署的文件中寻找什么来说明?

How I am wondering whether the version is still not getting deployed. What would I be looking for in the deployed files to tell?

部署中确实包含以下文件

Deployment does include the following files

52,816 dotnet-aspnet-codegenerator-design.dll 689584 Microsoft.CodeAnalysis.CSharp.Workspaces.dll 2,624,944 Microsoft.CodeAnalysis.Workspaces.dll 23,632 Microsoft.VisualStudio.Web.CodeGeneration.Contracts.dll 73,296 Microsoft.VisualStudio.Web.CodeGeneration.Core.dll 35,408 Microsoft.VisualStudio.Web.CodeGeneration.dll 69,200 Microsoft.VisualStudio.Web.CodeGeneration.EntityFrameworkCore.dll 28,752 Microsoft.VisualStudio.Web.CodeGeneration.Templating.dll 34,896 Microsoft.VisualStudio.Web.CodeGeneration.Utils.dll 157,776 Microsoft.VisualStudio.Web.CodeGenerators.Mvc.dll

52,816 dotnet-aspnet-codegenerator-design.dll 689,584 Microsoft.CodeAnalysis.CSharp.Workspaces.dll 2,624,944 Microsoft.CodeAnalysis.Workspaces.dll 23,632 Microsoft.VisualStudio.Web.CodeGeneration.Contracts.dll 73,296 Microsoft.VisualStudio.Web.CodeGeneration.Core.dll 35,408 Microsoft.VisualStudio.Web.CodeGeneration.dll 69,200 Microsoft.VisualStudio.Web.CodeGeneration.EntityFrameworkCore.dll 28,752 Microsoft.VisualStudio.Web.CodeGeneration.Templating.dll 34,896 Microsoft.VisualStudio.Web.CodeGeneration.Utils.dll 157,776 Microsoft.VisualStudio.Web.CodeGenerators.Mvc.dll

当我登录到计算机时，将在上面部署代码并键入

When I login to the machine the code is deployed on and type

dotnet .\myapi.dll  

错误是

It was not possible to find any compatible framework version
The specified framework 'Microsoft.AspNetCore.App', version '2.1.5' was not found.
  - Check application dependencies and target a framework version installed at:
      C:\Program Files\dotnet\
  - Installing .NET Core prerequisites might help resolve this problem:
      http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
  - The .NET Core framework and SDK can be installed from:
      https://aka.ms/dotnet-download

事件日志显示

如何确保已部署dotnet?

How do I ensure dotnet is deployed?

[更新]

我看到c:\ program files \ dotnet.exe是版本2.1.26919.1

I see that c:\program files\dotnet.exe is version 2.1.26919.1

但是我已经安装了.Net Core Runtime 2.1.5(x64) 我可以说它已安装，因为当我重新运行安装程序时，它会询问我是否要修复或卸载.

However I have installed .Net Core Runtime 2.1.5 (x64) I can tell that it is installed because when I re-run the installer it asks whether I want to repair or uninstall.

我想因为api在IIS下运行，所以不需要dotnet.exe吗?

I suppose that since the api is running under IIS it does not need dotnet.exe ?

计算机正在运行Windows 2012 Server R2

The machine is running Windows 2012 Server R2

推荐答案

我跑步时

dotnet运行.\ myapi.dll

dotnet run .\myapi.dll

我知道了

Did you mean to run dotnet SDK commands?
Please install dotnet SDK from: go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409

当我转到URL时，它安装了SDK 2.1.403

when I went to the URL it installed SDK 2.1.403

有效.
