python - 将错误从 Python 返回到 PowerShell？

Question

我在 PowerShell 中运行多个 Python 脚本，并且我希望在 Python 脚本中的特定条件下通知 PowerShell 主脚本。就像从 Python 中抛出错误并使用 PowerShell 捕获它一样。

Python 示例：

import os
print "Running Python script ..."
raise Exception("This Error is coming from Python")

和 PowerShell 主脚本：

$ErrorActionPreference = 'Stop'
try {
    python runThisScript.py -ErrorAction Stop
    # Write-Error -Message 'Oh no! An error!'
    Write-Host "What is that?"
} catch {
    Write-Host $_.Exception.Message -ForegroundColor Green
    throw [System.Exception] "Python scrip XXX failed"
} finally {
    Write-Host "This is the final block ..."
}

但这不起作用。它将显示：

Running Python script ...
Traceback (most recent call last):
  File "runThisScript.py", line 5, in <module>
    raise Exception("This Error is coming from Python")
Exception: This Error is coming from Python
What is that?
This is the final block ...

如果我取消注释该行，Write-Error -Message 'Oh no! An error!'这就是我想要看到的（错误是由 PowerShell 捕获和处理的）。

Oh no! An error!
This is the final block ...
Python scrip XXX failed
At C:\Automation\general_stuff\tc\mainTestRunner.ps1:12 char:5
+     throw [System.Exception] "Python scrip XXX failed"
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], Exception
    + FullyQualifiedErrorId : Python scrip XXX failed

预先感谢您的意见。
