我已经问过一个有点相关的问题here。

我在一个主文件中的不同文件点中有一堆函数，我如何将主文件中的这些函数称为作业？

这里是func1.ps1：

function FOO { write-output "HEY" }

这里是func2.ps1：

function FOO2 { write-output "HEY2" }

这里是 testjobsMain.ps1

$Functions = {
    . .\func1.ps1
    . .\func2.ps1
}

$var = Start-Job -InitializationScript $Functions -ScriptBlock { FOO } | Wait-Job | Receive-Job

$var

当我运行 testjobsMain.ps1 时出现此错误：

. : The term '.\func1.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the
name, or if a path was included, verify that the path is correct and try again.

    + FullyQualifiedErrorId : CommandNotFoundException

【问题讨论】：

您是否尝试过使用完整（而非相对）路径？即：. c:\func1.ps1
该死的就是这样。有没有办法可以使用函数文件的相对路径？它们都将位于同一个文件夹中。
在下面查看我的答案。相信我，我对 PS 相对/绝对路径感到很痛苦。
Here 是一个很好的同时点源多个文件的例子。

【解决方案1】：

绝对路径对我有用：

$Functions = {
    . c:\foo.ps1
}
$var = Start-Job -InitializationScript $Functions -ScriptBlock { FOO } | Wait-Job | Receive-Job
$var

如果需要，在 testjobsMain.ps1 中，您可以使用 $PSScriptRoot 自动变量将相对路径替换为绝对路径。例如：

$Functions = [scriptblock]::Create(" . $PSScriptRoot\foo.ps1 `n . $PSScriptRoot\bar.ps1 `n")
