c# - TFS 2018 构建失败，错误 MSB6006 : "csc.exe" exited with code 1

Question

我最近构建了一个新的 TFS 2018(更新 3)服务器并添加了 Visual Studio 构建工具(v15.7.1)。创建一个非常简单的 C# 项目后，服务器构建失败，并显示 Error MSB6006: "csc.exe"exited with code 1。我打开调试并发现了错误

Could not load file or assembly 'Microsoft.CodeAnalysis.CSharp, Version=2.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. (TaskId:32)

我的项目没有引用此库，并且我在项目级别关闭了代码分析，因此我认为这是 VS 构建工具的问题。有谁知道解决此问题的方法或方法吗？

我还注意到 VS Build Tools (v15.8) 的更新版本。我还没有尝试更新构建服务器，因为生成离线包、压缩、上传等的复杂性很高，但如果找不到短期修复，这将是我的下一步努力。

基本上，我们的新服务器已经死了，没有解决方案，所以我希望有人能在这里找到答案，否则，我可能最终会放弃这一切以获得更可靠的东西。

Answer 1

似乎是版本 15.7.1 中的错误。目前尚不清楚是否有任何其他版本受到此错误的影响，但升级到 VS Build Tools 到 15.8.2 解决了该问题。

要发现错误 MSB6006:“csc.exe”以代码 1 退出的根本问题，请在 MSBuild 参数中设置以下标志:

/v:diag

这将产生类似于以下内容的内容:
