Question

我有一个在本地构建和运行良好的项目。但是，当我将其推送到我的服务器（Windows Server 2012 R2）时，它无法构建。它没有给我任何关于它为什么失败的细节。即使我添加了详细的标志。

PS C：\ projectroot＆gt; dotnet -v build

遥测是：已启用

对象引用未设置为对象的实例。

我在事件日志中看不到任何内容。有没有其他地方我可以找到错误信息来缩小范围？还有其他想法吗？

我怀疑它可能是一些缺失的依赖，因为它在本地工作，但不知道接下来要去哪里看出来。

这是我的project.json的副本。在尝试单独构建项目的解决方法之前，我尝试了几种组合。

您是否在跑步前尝试清理项目？因为在您自己的笔记本电脑/工作站中构建时的“缓存”文件可能已在服务器上重复使用。

在你的project.json中，

我注意到你正在使用461框架。不确定.NET Core是否也使用它，因为我一直在使用这个

 "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
}

dotnet build throw nullreference exception
