从脚本模块中的嵌套模块调用函数并不总是触发模块自动加载

Question

如果我使用嵌套模块创建清单模块,则在第一个之后的所有嵌套模块中的导出函数不会出现在可用命令列表中,并且不会触发模块自动加载.

当我运行"Get-Module -ListAvailable"时,它们也不会出现.

只有第一个嵌套模块中的导出函数才会出现在命令列表中.

如果我明确导入模块,则所有导出的函数都可用.

在下面的示例中,在显式导入模块之前,Update-LegacyServices不可用.

我可以使它的唯一方法是将我的模块文件重命名为ps1而不是psm1,并将它们包含在ScriptsToProcess中,这似乎是一个坏主意.

第1单元(Build\Build.psm1)

function Update-LegacyServices()
{
    echo "Update"
}

Export-ModuleMember -Function Update-LegacyServices

第2单元(database\Database.psm1)

Function Get-Backup($directory, $name)
{
    echo "Get-Backup"
}

Export-ModuleMember -Function Get-Backup

Answer 1

我的 .psd1 文件中有这一行

FunctionsToExport = 'FuncFromMainPsm1 FuncFromSecondPsm1'

这是我从 Powershell Tools for Visual Studio 生成的行中推断出的：

# Functions to export from this module
FunctionsToExport = '*'

这导致我Get-Module -ListAvailable展示了看起来正确的东西

Script     1.0        MyMModule                  FuncFromMainPsm1 FuncFromSecondPsm1

但是当我打电话时，FuncFromSecondPsm1我会收到“术语‘FuncFromSecondPsm1’无法识别......”。

所以我将导出行更改为

FunctionsToExport = @('FuncFromMainPsm1', 'FuncFromSecondPsm1')

现在一切正常了。我可以在模块加载后调用这两个函数，无论是通过 autoload 还是Import-Module.

我已经尝试过使用和不使用两者ModuleList并FileList设置。它们没有什么区别。
