使PowerShell脚本运行的cmdlet在全球范围内

Question

我写了下面的PowerShell脚本：

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

与此脚本唯一的问题是，导入模块仅适用该脚本的范围内 - 它不会导入模块在全球范围内。有没有什么办法让脚本导入模块，以便在脚本结束后保持它？

注意：dot-sourcing像这样：. Reload-Module MyModuleName不起作用。

从PowerShell帮助：

-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还增加了-Scope参数，它更多的是一种小将军：

-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：上述帮助片段是从V3。 0这是我在我的系统上安装的。 v2.0的帮助可在http://msdn.microsoft.com/en-us/library/windows/desktop/dd819454.aspx。如果可以的话，我衷心推荐使用PowerShell v3.0，如果仅仅是因为新的ISE。
