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

当它尝试运行dotnet bundle时出现错误

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

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，但我发现只有这个版本可以工作。

    - 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
