Question

在尝试运行dotnet build命令时，我在Amazon Linux中遇到此错误。我正在尝试使用sonarqube .net核心扫描程序，并将其作为运行dotnet build命令的一部分。

sudo dotnet build --no-restore --verbosity d --no-dependencies

Project file contains ToolsVersion="". This toolset may be unknown or missing, in which case you may be able to resolve this by installing the appropriate version of MSBuild, or the build may have been forced to a particular ToolsVersion for policy reasons.

我的.csproj文件如下所示

```
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
   <TargetFramework>netcoreapp2.0</TargetFramework>
 </PropertyGroup>
  <ItemGroup>  
    <Compile Include="ReliabilityMain.cs"/>
    <PackageReference Include="Microsoft.Net.Compilers" Version="2.4.0" />
  </ItemGroup>  
  <Target Name="Build">  
    <Csc Sources="@(Compile)"
    TargetType="library"
     OutputAssembly="$(builtdir)\$(MSBuildProjectName).dll"
    />    
  </Target>  
</Project>  
```

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

的引用

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

希望对您有帮助。
