.net - dotnet rosalyn 编译器错误 MSB6006：“csc.exe”以代码 8 退出

问题描述

在尝试运行 dotnet build 命令时，我在 amazon linux 中遇到了这个错误。我正在尝试使用 sonarqube .net 核心扫描仪，并将其作为运行 dotnet build 命令的一部分。

sudo dotnet build --no-restore --verbosity d --no-dependencies
Microsoft (R) Build Engine version 15.3.409.57025 for .NET Core

我的 .csproj 文件如下所示

   <TargetFramework>netcoreapp2.0</TargetFramework>
 </PropertyGroup>

  </ItemGroup>  
  <Target Name="Build">  
    <Csc Sources="@(Compile)"
    TargetType="library"
     OutputAssembly="$(builtdir)\$(MSBuildProjectName).dll"
    />    
  </Target>  
</Project>  
```

解决方案

当我尝试从 VS Code 而不是 Visual Studio（macOS 环境）构建我的项目时，我遇到了这个问题。经过一些不成功的研究，我刚刚删除了对Microsoft.Net.Compilers

删除它后，我可以从 VS Code 和 Visual Studio for MAC 运行、构建和调试。

我希望它有所帮助。
