.NET 6.0 预览版、dotnet 包、Github 操作失败

问题描述

鉴于此（缩写）Github 工作流程

   steps:
    - uses: actions/checkout@v2
    - uses: actions/setup-node@v2    
    - uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '6.0.100-preview.4.21255.9'
        include-prerelease: true
    - uses: darenm/Setup-VSTest@v1

    - name: Build
      run: dotnet publish SendExplorerPlus.sln /p:Configuration=Release /p:PublishProfile=local /verbosity:minimal

我在尝试运行 dotnet bundle 时遇到错误

Run dotnet publish SendExplorerPlus.sln /p:Configuration=Release /p:PublishProfile=local /verbosity:minimal

在过去的几个小时里，我一直在玩弄这个工作流，但找不到解决方法。有什么想法吗？

解决方法

我通过添加特定版本的 .NET SDK 解决了这个问题。即2.2.106。尝试了其他版本的 SDK，但这是我发现的唯一一个。

    - uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '2.2.106'
    - uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '6.0.100-preview.4.21255.9'
        include-prerelease: true
