我有一个模块,我称之为xyz.ps.core
。它导出一个函数-Get-PullRequestsFromCommitIds
我修复了该功能中的一个错误,重新发布了该模块,重新安装并重新导入了该功能,但该功能仍引用该模块的旧版本。
请注意:
C:\xyz\tip [master ≡]> Get-Command Get-PullRequestsFromCommitIds | ft -AutoSize
CommandType Name Version Source
----------- ---- ------- ------
Function Get-PullRequestsFromCommitIds 1.0.19107.4 xyz.ps.core
如您所见,该函数来自1.0.19107.4
版
C:\xyz\tip [master ≡]> get-module xyz.ps.core | ft -AutoSize
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Manifest 1.0.19107.7 xyz.ps.core {Assert-ExtractionDestFolder, Assert-PullRequestMatchesFolder, Backup-Database, Connect-OctopusToTfs...}
C:\xyz\tip [master ≡]> get-module xyz.ps.core -ListAvailable | ft -AutoSize
Directory: C:\Users\mkharitonov\Documents\WindowsPowerShell\Modules
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Manifest 1.0.19107.7 xyz.PS.Core {Assert-ExtractionDestFolder, Assert-PullRequestMatchesFolder, Backup-Database, Connect-OctopusToTfs...}
但是模块版本已经在1.0.19107.7
上。但是,好的,我有一个刷新模块的功能,即使它已经安装到相同的版本:
C:\xyz\tip [master ≡]> (get-command Use-Module).ScriptBlock
param([Parameter(Mandatory)]$Name)
if ($VerbosePreference -ne 'Continue')
{
Write-Host -ForegroundColor Cyan -NoNewline "Using the latest version of $Name ... "
}
Write-Verbose "Uninstalling all the versions of $Name ..."
Uninstall-Module $Name -AllVersions -Force -ErrorAction SilentlyContinue
Remove-Module $Name -Force -ErrorAction SilentlyContinue
Write-Verbose "Installing the latest version of $Name ..."
Install-Module $Name -Scope CurrentUser -Force
Write-Verbose "Importing $Name into the current session ..."
Import-Module $Name -Force
if ($VerbosePreference -ne 'Continue')
{
Write-Host -ForegroundColor Cyan (Get-Module $Name).Version
}
让我们现在使用它:
C:\xyz\tip [master ≡]> use-module xyz.ps.core
Using the latest version of xyz.ps.core ... 1.0.19107.7
让我们检查函数源:
C:\xyz\tip [master ≡]> Get-Command Get-PullRequestsFromCommitIds | ft -AutoSize
CommandType Name Version Source
----------- ---- ------- ------
Function Get-PullRequestsFromCommitIds 1.0.19107.4 xyz.ps.core
还是旧的。请注意,在新的Powershell窗口中,该功能取自模块的当前版本。
是否可以在不关闭powershell的情况下刷新功能?
答案 0 :(得分:2)
行为全部为about scopes。 TLDR:
会话,模块和嵌套提示是独立的环境, 但它们不是会话中全局作用域的子作用域。
基本上,由于模块是独立的环境,而不是子作用域,因此它们无法将模块导入“父”脚本作用域。 即使使用了-Force
。
让我们在模块内测试范围:
sampleModule.psm1
Function Test-Import {
param([Parameter(Mandatory)]$Name)
Write-Host "List Loaded modules before"
Get-Module
Write-Host "Importing $Name into the current session ..."
Import-Module $Name -Force
Write-Host "Module Version $((Get-Module $Name).Version)"
Write-Host "Loaded Modules After"
#List Loaded modules after
Get-Module
}
#Only present desired functions
Export-ModuleMember -Function Test-Import
如果我们从简单的空白测试开始(为了简便起见,我删除了无关的模块):
PS C:> #Clean state - Nothing Loaded for demonstration
PS C:> Get-Module
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
PS C:> Import-Module .\sampleModule.psm1
PS C:> Get-Module
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Script 0.0 Test-Module {Test-Import}
PS C:> Test-Import ActiveDirectory
List Loaded modules before
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Script 0.0 Test-Module {Test-Import}
Importing ActiveDirectory into the current session ...
Module Version 1.0.1.0
Loaded Modules After
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Manifest 1.0.1.0 ActiveDirectory {Add-ADCentralAccessPolicyMember, Add-ADComputerServiceAccount, Add-ADDomainControllerPasswordReplicationPolicy, Add-ADFineGrainedPasswordPolicySubject...}
Script 0.0 Test-Module {Test-Import}
在这里,我们注意到ActiveDirectory模块在该函数的开头不存在,但实际上是在该函数的末尾加载的,并报告了正确的版本。现在让我们看看它是否已加载:
PS C:> Get-Module
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Script 0.0 Test-Module {Test-Import}
我们可以看到,由于模块在自己的独立环境中运行,因此我们成功地将模块(在此示例中为ActiveDirectory)导入了模块作用域,但没有像您期望的那样导入到本地作用域。
解决此范围问题的唯一方法是将模块导入全局范围
通过添加-Global
,例如:
Import-Module $Name -Force -Global
在示例脚本中更改这一行,然后重新导入:
PS C:> Import-Module .\sampleModule.psm1 -Force
PS C:> Get-Module
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Script 0.0 Test-Module {Test-Import}
PS C:> Test-Import ActiveDirectory
List Loaded modules before
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Script 0.0 Test-Module {Test-Import}
Importing ActiveDirectory into the current session ...
Module Version 1.0.1.0
Loaded Modules After
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Manifest 1.0.1.0 ActiveDirectory {Add-ADCentralAccessPolicyMember, Add-ADComputerServiceAccount, Add-ADDomainControllerPasswordReplicationPolicy, Add-ADFineGrainedPasswordPolicySubject...}
Script 0.0 Test-Module {Test-Import}
与以前相同...现在让我们检查它是否正确加载:
PS C:> Get-Module
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Manifest 1.0.1.0 ActiveDirectory {Add-ADCentralAccessPolicyMember, Add-ADComputerServiceAccount, Add-ADDomainControllerPasswordReplicationPolicy, Add-ADFineGrainedPasswordPolicySubject...}
Script 0.0 Test-Module {Test-Import}
成功!
