升级到.Net Core 2.0后，打包期间出现“执行Lambda打包的未知错误”错误

Question

我在.Net Core Lambda项目中将目标框架从netcoreapp1.0更改为netcoreapp2.0。

打包lambda时，执行命令dotnet lambda package -c Release -f netcoreapp2.0 ：

执行Lambda打包时发生未知错误：找不到路径的一部分

dotnet lambda package -c Release -f netcoreapp2.0

Answer 1

似乎发生了此问题，因为我正在使用旧版本的Amazon.Lambda.Tools ：

<ItemGroup>
    <DotNetCliToolReference Include="Amazon.Lambda.Tools" Version="1.7.0" />
</ItemGroup>

手动将其更改为最新版本即可修复：

<ItemGroup>
    <DotNetCliToolReference Include="Amazon.Lambda.Tools" Version="2.1.2" />
</ItemGroup>

现在的输出如下所示：
