使PowerShell腳本運行的cmdlet在全球範圍內

Question

我寫了下面的PowerShell腳本：

function Reload-Module ([string]$moduleName) { 
    $module = Get-Module $moduleName 
    Remove-Module $moduleName -ErrorAction SilentlyContinue 
    Import-Module $module 
} 

與此腳本唯一的問題是，導入模塊僅適用該腳本的範圍內 - 它不會導入模塊在全球範圍內。有沒有什麼辦法讓腳本導入模塊，以便在腳本結束後保持它？

注意：dot-sourcing像這樣：. Reload-Module MyModuleName不起作用。

從PowerShell幫助：

-Global [<SwitchParameter>] 
Imports modules into the global session state so they are available to all commands in the session. By 
default, the commands in a module, including commands from nested modules, are imported into the 
caller's session state. To restrict the commands that a module exports, use an Export-ModuleMember 
command in the script module. 

The Global parameter is equivalent to the Scope parameter with a value of Global. 


Required?     false 
Position?     named 
Default value    False 
Accept pipeline input?  false 
Accept wildcard characters? false 

V3還增加了-Scope參數，它更多的是一種小將軍：

-Scope <String> 
Imports the module only into the specified scope. 

Valid values are: 

-- Global: Available to all commands in the session. Equivalent to the 
Global parameter. 

-- Local: Available only in the current scope. 

By default, the module is imported into the current scope, which could be 
a script or module. 

This parameter is introduced in Windows PowerShell 3.0. 

Required?     false 
Position?     named 
Default value    Current scope 
Accept pipeline input?  false 
Accept wildcard characters? false 

注：上述幫助片段是從V3。 0這是我在我的系統上安裝的。 v2.0的幫助可在http://msdn.microsoft.com/en-us/library/windows/desktop/dd819454.aspx。如果可以的話，我衷心推薦使用PowerShell v3.0，如果僅僅是因爲新的ISE。
