【问题描述】:
我正在创建一个脚本模块并使用清单来导出脚本成员并设置其他模块属性。我几乎遵循了我找到的每个示例清单,甚至使用 New-ModuleManifest 来创建具有我想要的属性的基线清单,但我仍然无法将我想要导出的变量实际导出。
这里的目的是在清单中进行所有声明,而不必在模块脚本中使用Export-ModuleMember。
这里是脚本模块:
#
# Widget.psm1
#
[System.Random]$rGen = New-Object System.Random;
[string]$WidgetBaseName = $null;
[string]$WidgetColor = "Blue";
function Get-WidgetName
{
param
(
[Parameter(Mandatory=$true)]
[string]$widgetName,
[switch]$appendRandomNumber
)
if (![string]::IsNullOrEmpty($WidgetBaseName))
{
$widgetName = $WidgetBaseName + $widgetName;
}
if ($appendRandomNumber)
{
return [string]::Format("{0}{1:D4}", $widgetName, $rGen.Next(10000));
}
else
{
return $widgetName;
}
}
function Get-WidgetBlessing()
{
return [string]::Format("A thousand blessings upon your {0} widget!", $WidgetColor);
}
这是清单:
#
# Widget.psd1
#
@{
# Script module or binary module file associated with this manifest
RootModule = 'Widget.psm1'
# Version number of this module.
ModuleVersion = '0.0.0.1'
# ID used to uniquely identify this module
GUID = 'c4437164-ea47-4148-97ed-48737bd5824d'
# Author of this module
Author = 'Widget Developer'
# Company or vendor of this module
CompanyName = 'Fictional Company Inc.'

# Processor architecture (None, X86, Amd64) required by this module
# ProcessorArchitecture = ''
# Modules that must be imported into the global environment prior to importing this module
# RequiredModules = @()

# ScriptsToProcess = @()
# Type files (.ps1xml) to be loaded when importing this module
# TypesToProcess = @()
# Format files (.ps1xml) to be loaded when importing this module
# FormatsToProcess = @()
# Modules to import as nested modules of the module specified in RootModule/ModuleToProcess
# NestedModules = @()
# Functions to export from this module
FunctionsToExport = @( "Get-WidgetName", "Get-WidgetBlessing" )
# Cmdlets to export from this module
# CmdletsToExport = @()
# Variables to export from this module
VariablesToExport = 'WidgetBaseName', 'WidgetColor'
# Aliases to export from this module
AliasesToExport = '*'
# List of all modules packaged with this module
# ModuleList = @()
# List of all files packaged with this module
# FileList = @()
# Private data to pass to the module specified in RootModule/ModuleToProcess
# PrivateData = ''
# HelpInfo URI of this module
# HelpInfoURI = ''
# Default prefix for commands exported from this module. Override the default prefix using Import-Module -Prefix.
# DefaultCommandPrefix = ''
}
要检查导出了哪些成员,我在 PowerShell 窗口中运行以下命令:
Import-Module Widget
Get-Module -Name Widget | fl
这是输出。请注意明显没有任何导出的变量。
Name : Widget
Path : D:\SRE\PowerShell\Widget\Widget.psm1
Description : Widget Module
ModuleType : Script
Version : 0.0.0.1
NestedModules : {}
ExportedFunctions : {Get-WidgetBlessing, Get-WidgetName}
ExportedCmdlets :
ExportedVariables :
ExportedAliases :
这是为什么?我正在使用 New-ModuleManifest 生成的清单 (New-ModuleManifest -VariablesToExport WidgetBaseName WidgetColor)。该工具是否损坏,或者清单中是否有其他东西导致了这种行为?
更新:
我在模块脚本的末尾添加了以下行:
Export-ModuleMember -Variable WidgetBaseName, WidgetColor
我在清单文件中将VariablesToExport 的值更改为“*”。
现在,当我导入模块并按上述方式运行检查时,我得到了这个:
Name : Widget
Path : D:\SRE\PowerShell\Widget\Widget.psm1
Description : Widget Module
ModuleType : Script
Version : 0.0.0.1
NestedModules : {}
ExportedFunctions :
ExportedCmdlets :
ExportedVariables : {WidgetBaseName, WidgetColor}
ExportedAliases :
...我导出的函数到哪里去了?
【问题讨论】:
-
没有损坏;你必须使用
Export-ModuleMember;查看链接的副本。 -
这是一个链接,扩展了@briantist 所说的内容:itidea.nl/index.php/…。我以前从未尝试过导出变量;那个 SO 帖子和这个链接中描述的行为绝对是违反直觉的恕我直言。
-
@JasonBoyd 这是一篇很棒的文章
-
我不同意这是与其他文章的重复。另一篇文章仅讨论使用
Export-ModuleMember导出,根本不讨论清单。这里的要点是不能使用清单来声明要导出的变量吗?
