我正在尝试使用 Powershell 中的 Task 类来异步运行操作。但我得到以下异常:
Id : 1
Exception : System.AggregateException: One or more errors occurred. ---> System.Management.Automation.PSInvalidOperationException: There is no Runspace available to
run scripts in this thread. You can provide one in the DefaultRunspace property of the System.Management.Automation.Runspaces.Runspace type. The script
block you attempted to invoke was: Write-Host "hey!"
at System.Management.Automation.ScriptBlock.InvokeAsDelegateHelper(Object dollarUnder, Object dollarThis, Object[] args)
at System.Threading.Tasks.Task.Execute()

我的代码:
$delegate = [System.Action]{ Write-Host "Test" }
[System.Threading.Tasks.Task]::Run($delegate)
