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内 - 它不会在全局范围内导入模块。有没有办法让脚本导入一个模块，以便在脚本完成后它仍然存在？

注意：像这样的点源：. Reload-Module MyModuleName不起作用。

来自 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，这个参数更通用一点：

-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：上面的帮助片段来自 v3.0，这是我在我的系统上安装的。v2.0 帮助位于http://msdn.microsoft.com/en-us/library/windows/desktop/dd819454.aspx。如果可以的话，我衷心建议您购买 PowerShell v3.0，如果仅仅是因为新的 ISE。
