Visual Studio $(ProjectDir) 为空字符串

Question

我正在使用 Visual Studio 2017，我想添加一个 post-build 命令。当我转到 'Macros' window 时，我看到正确的路径 coresponging 到 $(ProjectDir) 变量。所以我添加了命令：

$(ProjectDir)ClientApp\npm run build

但是当我执行构建时出现以下错误：

The command 'ClientApp\npm run build'exited with code 3.

我将 MSBuild 详细更改为诊断并在输出中 window 我看到：

1>Target "PostBuildEvent" in file "C:\Program Files (x86)\Microsoft Visual Studio17\Community\MSBuild.0\Bin\Microsoft.Common.CurrentVersion.targets": 1> Using "Exec" task from assembly "Microsoft.Build.Tasks.Core, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". 1> Task "Exec" 1> Task Parameter:WorkingDirectory=bin\Debug\netcoreapp1.1\ 1> Task Parameter:Command=ClientApp\npm run build 1> ClientApp\npm run build 1> The system cannot find the path specified. 1>
C:\Program Files (x86)\Microsoft Visual Studio17\Community\MSBuild.0\Bin\Microsoft.Common.CurrentVersion.targets(4933,5): error MSB3073: The command "ClientApp\npm run build" exited with code 3. 1> Done executing task "Exec" -- FAILED.

在目标文件中我得到了这些行：

  <Target
      Name="PostBuildEvent"
      Condition="'$(PostBuildEvent)' != '' and ('$(RunPostBuildEvent)' != 'OnOutputUpdated' or '$(_AssemblyTimestampBeforeCompile)' != '$(_AssemblyTimestampAfterCompile)')"
      DependsOnTargets="$(PostBuildEventDependsOn)">

    <Exec WorkingDirectory="$(OutDir)" Command="$(PostBuildEvent)" />

  </Target>

我可以将工作目录从 $(OutDir) 更改为 $(ProjectDir) 吗？如何更改？

我有什么想法是错误的吗？注意 - 我在 BAT 文件中添加了命令，只是为了测试，但结果是一样的
