在 GitHub 个操作中获得 "StandardOutputEncoding is only supported when standard output is redirected"

Question

我运行 gitversion.exe 作为 GitHub 操作工作流程的一部分 Windows 使用 pwsh:

$versionInfo = (& .\gitversion.exe) | ConvertFrom-Json

虽然在我的本地机器上工作得很好，但它在动作运行器上失败了：

ResourceUnavailable: D:\a\azure-pipelines-pre-and-post-tasks\azure-pipelines-pre-and-post-tasks\build.ps1:178
Line |
 178 |  $versionInfo = (& .\gitversion.exe) | ConvertFrom-Json
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Program 'gitversion.exe' failed to run: StandardOutputEncoding is only supported when standard output
     | is redirected.At
     | D:\a\azure-pipelines-pre-and-post-tasks\azure-pipelines-pre-and-post-tasks\build.ps1:178 char:17 +
     | $versionInfo = (& .\gitversion.exe) | ConvertFrom-Json +                 ~~~~~~~~~~~~~~~~~~.

我是运行其他可执行文件并在同一个脚本中毫无问题地捕获它们的输出，所以 gitversion 肯定有一些我不完全理解的特别之处。

好吧，这是出乎意料的。首先，我偶然发现了更改 PowerShell 控制台输入和输出编码的提示：

[console]::InputEncoding = [console]::OutputEncoding = New-Object System.Text.UTF8Encoding

这揭示了一个新问题，即 gitversion.exe 不是有效的 windows 可执行文件。原来是LFS指针文件

ResourceUnavailable: D:\a\azure-pipelines-pre-and-post-tasks\azure-pipelines-pre-and-post-tasks\build.ps1:179
Line |
 179 |  $versionInfo = & .\gitversion.exe | ConvertFrom-Json
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Program 'gitversion.exe' failed to run: An error occurred trying to start process
     | 'D:\a\azure-pipelines-pre-and-post-tasks\azure-pipelines-pre-and-post-tasks\gitversion.exe' with
     | working directory 'D:\a\azure-pipelines-pre-and-post-tasks\azure-pipelines-pre-and-post-tasks'. The
     | specified executable is not a valid application for this OS platform.

我忘记补充了：

with:
  lfs: true

我的结帐任务：

steps:
- uses: actions/checkout@v2
  with:
    lfs: true

无论操作系统抛出什么错误，都会导致此 post 标题中的错误。但真正的问题是缺少实际的可执行文件。
