AWS Lambda和.NET Core-使用Linux运行时吗？ [英] AWS Lambda and .NET Core - Using a Linux Runtime?

问题描述

我正在编写C＃（.NET Core）中的Alexa技能，该技能可通过AWS Lambda函数（在Amazon Linux上运行）运行。当我编译项目（ dotnet发布）时，出现错误：

I am writing an Alexa skill in C# (.NET Core) to be run from an AWS Lambda function (which runs on Amazon Linux). When I compile the project (dotnet publish), I get the error:

找不到运行时目标框架'.NETCoreApp，Version = v1.0'
与目标运行时之一兼容：'win10- x64，win81-x64，
win8-x64，win7-x64'。可能的原因：

Can not find runtime target for framework '.NETCoreApp,Version=v1.0' compatible with one of the target runtimes: 'win10- x64, win81-x64, win8-x64, win7-x64'. Possible causes:

1. 项目尚未还原或还原失败-运行dotnet
   restore


2. 该项目未在运行时部分中列出 win10-x64，win81-x64，
   win8-x64，win7-x64之一。


3. 您可能试图
   发布不支持的库。使用dotnet pack来
   分发库。

如果我指定Windows运行时（例如作为 win10-x64 ），它将可以很好地编译，但是我的依赖项之一（Google Sheets API）由于位于基于Linux的Lambda上而在运行时出现了问题。使用Linux运行时（例如debian.8-x64）将导致相同的编译错误。

If I specify a Windows runtime (such as win10-x64), it will compile fine, however one of my dependencies (Google Sheets API) has problems at runtime due to being on the Linux-based Lambda. Using a Linux runtime (such as debian.8-x64) will cause the same compile error.

当AWS开发工具包自身的平台为Linux的？我觉得我缺少明显的东西，一旦有人向我指出这个问题，我就会高兴地面对。

Why would the AWS SDK require a Windows runtime, when its own platform is Linux? I feel like I'm missing something obvious and will happily face palm the moment someone points the issue out to me.

我的project.json文件（主应用程序和）。 NET Core类库项目）：

My project.json files (main app, and .NET Core class library project):

AlexaProj

{
  "version": "1.0.0-*",
  "buildOptions": {
  },

  "dependencies": {
    "Microsoft.NETCore.App": "1.1.1",
    "Amazon.Lambda.Core": "1.0.0*",
    "Amazon.Lambda.Serialization.Json": "1.0.1",
    "Amazon.Lambda.Tools": {

      "version": "1.3.0-preview1"
    },
    "Slight.Alexa.Core": "1.0.10-beta",

    }
  }
}

推荐答案

我发现 JeffRCorp在AWS论坛上发布了有关类似问题的信息，他们的步骤也对我有用。

I found JeffRCorp posted on the AWS forums about having a similar issue, and their steps worked for me too.

首先，我编辑了 project.json 并将 Microsoft.NETCore.App 依赖项移至了 frameworks 部分（尽管我不确定这是否会有所作为）。我还删除了运行时部分。最终project.json：

First I edited project.json and moved the Microsoft.NETCore.App dependency into the frameworks section (although I'm not sure if this makes a difference). I also removed the runtimes section. Final project.json:

{
  "version": "1.0.0-*",
  "buildOptions": {
  },

  "dependencies": {
    "Amazon.Lambda.Core": "1.0.0*",
    "Amazon.Lambda.Serialization.Json": "1.0.1",
    "Amazon.Lambda.Tools": {
      "type": "build",
      "version": "1.3.0-preview1"
    },
    "Slight.Alexa.Core": "1.0.10-beta",
    "AlexaProjLib": "1.0.0-*"
  },

  "tools": {
    "Amazon.Lambda.Tools": "1.3.0-preview1"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": "dnxcore50",
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.1.1"
        }
      }
    }
  }
}

然后我运行了 dotnet lambda软件包，该软件包在 bin中构建了一个.zip文件/Release/netcoreapp1.0 目录。通过AWS控制台将此文件上传到AWS Lambda，瞧！

I then ran dotnet lambda package which built a .zip file in the bin/Release/netcoreapp1.0 directory. Uploaded this to AWS Lambda via the AWS Console and voila!
