錯誤NU1107版本沖突檢測到Microsoft.CodeAnalysis.Common

Question

將測試項目從.NET Core 2.0升級到2.1之后，我開始在構建過程中遇到以下錯誤：

Error       Package restore failed. Rolling back package changes for 'Api.Tests'.

Error   NU1107  Version conflict detected for Microsoft.CodeAnalysis.Common. Install/reference Microsoft.CodeAnalysis.Common 2.8.2 directly to project Api.Tests to resolve this issue. 
    Api.Tests -> Api -> Microsoft.CodeAnalysis.Common (>= 2.8.2) 
    Api.Tests -> Microsoft.AspNetCore.Mvc 2.0.3 -> Microsoft.AspNetCore.Mvc.Localization 2.0.3 -> Microsoft.AspNetCore.Mvc.Razor 2.0.3 -> Microsoft.CodeAnalysis.CSharp 2.3.1 -> Microsoft.CodeAnalysis.Common (= 2.3.1).   Api.Tests

Error   NU1107  Version conflict detected for Microsoft.CodeAnalysis.Common. Install/reference Microsoft.CodeAnalysis.Common 2.8.2 directly to project Api.Tests to resolve this issue. 
    Api.Tests -> Api -> Microsoft.CodeAnalysis.Common (>= 2.8.2) 
    Api.Tests -> Microsoft.AspNetCore.Mvc 2.2.0-preview3-35497 -> Microsoft.AspNetCore.Mvc.Localization 2.2.0-preview3-35497 -> Microsoft.AspNetCore.Mvc.Razor 2.2.0-preview3-35497 -> Microsoft.CodeAnalysis.CSharp 2.8.0 -> Microsoft.CodeAnalysis.Common (= 2.8.0).  Api.Tests

我嘗試直接在項目中安裝Microsoft.CodeAnalysis.Common 2.8.2，但出現以下錯誤：

Restoring packages for Api.Tests.csproj...

對於如何解決這個問題，有任何的建議嗎？

Answer 1

要解決此問題，您必須顯式安裝

<PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.*" />

要么

<PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.*" />

測試項目，具體取決於您在API項目中使用的軟件包。
