Powershell自定义模块CommandNotFoundException

Question

当我导入我的模块时，我无法访问公开的成员。

将我的模块放在C:\Program Files\WindowsPowerShell\Modules。

当我在powershell中导入我的模块时： Import-Module StuiterModule -Verbose

然后输入Invoke-Reboot，它会出现以下错误：

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

+ Invoke-Reboot
+ ~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Invoke-Reboot:String [], CommandNotFoundExeption
    + FullyQualifiedErrorId : CommandNotFoundException

有没有人知道我做错了什么？

更新

当我将-Force置于导入模块后面时，一切正常。为什么这样，我该如何解决这个问题？

代码：

StuiterModule.psm1

$Public = @( Get-ChildItem -Path "$PSScriptRoot\Public\*.ps1" )
$Private = @( Get-ChildItem -Path "$PSScriptRoot\Private\*.ps1" )

@($Public + $Private) | ForEach-Object {
    Try {
        . $_.FullName
    } Catch {
        Write-Error -Message "Failed to import function $($_.FullName): $_"
    }
}

Export-ModuleMember -Function $Public.BaseName
