使PowerShell脚本在全局范围内运行cmdlet

Question

我编写了以下PowerShell脚本:

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

此脚本的唯一问题是Import-Module仅适用于该脚本的范围 - 它不会在全局范围内导入该模块.有没有办法让脚本导入一个模块,以便它在脚本完成后保持不变？

注意:像这样的点源:. 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还添加了-Scope参数,这更常见:

-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

注意:以上帮助代码段来自v3.0,这是我在系统上安装的内容.可从http://msdn.microsoft.com/en-us/library/windows/desktop/dd819454.aspx获取v2.0帮助.如果可以的话,我衷心建议您使用PowerShell v3.0,如果只是因为新的ISE.
