我一直在写一个PowerShell脚本。因为我想稍微模块化/组织一下我的代码，所以我决定尝试制作一些模块来分割我的脚本。
Powershell 5.1.14393.1066
现在我有一个主脚本，它导入了它需要的模块，但它似乎找不到我的函数Is-Template-Name-Set：

Is-Template-Name-Set : The term 'Is-Template-Name-Set' 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.
At C:\Users\niels\test1\TemplateScript.ps1:6 char:5
+ If (Is-Template-Name-Set) {
+     ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Is-Template-Name-Set:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Is-Template-Name-Set在UtilityTemplateModule中定义。模块文件（UtilityTemplateModule.psm1）：

Function Get-ScriptDirectory() {
    return Split-Path $script:MyInvocation.MyCommand.Path
}

Function Is-Template-Name-Set($templateName) {
    $templateName -And $templateName -is [String] -And -Not $templateName -eq ""
}

Export-ModuleMember -Function 'Get-*'
Export-ModuleMember -Function 'Is-*'

UtilityTemplateModule说明（UtilityTemplateModule.psd1文件）：

@{
ModuleVersion = '1.0'
GUID = '082fc8f7-4c7f-4d9f-84a8-b36c3610cdfe'
Author = 'Niels Bokmans'
CompanyName = 'Bluenotion'
Copyright = 'Copyright (c) 2017'
Description = 'General utilities used by the other template modules.'
# Functions to export from this module
FunctionsToExport = '*'

# Cmdlets to export from this module
CmdletsToExport = '*'

# Variables to export from this module
VariablesToExport = '*'

# Aliases to export from this module
AliasesToExport = '*'
}

我的主要脚本：

param([String]$templateName="")
Import-Module BuildTemplateModule
Import-Module CdnTemplateModule
Import-Module UtilityTemplateModule

If (Is-TemplateNameSet -templateName $templateName) {
    echo "Template name is set!"
    $templateId = GetTemplateId -templateName $templateName
    if (-Not $templateId -eq -1) {
        Restore-Packages
        Run-Build-Tasks
        Minify-Require-Js
        Clean-Downloaded-Dependencies
        Copy-Offline-Page
        #Deploy $response.templateId
    }
} else {
    echo "Template name not set!"
    exit
}

我对任何powershell工作都很陌生，我不知道为什么这个函数不被识别。我认为我做的是正确的，导出模块本身中的函数，也只是导出描述文件中的所有内容（？. psd 1文件）。
任何建议将不胜感激。
