powershell - 安装 posh-git 时遇到问题

Question

我想在笔记本电脑上安装 posh-git，但是当我尝试使用命令“PowerShellGet\Install-Module posh-git -Scope CurrentUser -AllowPrerelease -Force”安装时出现错误:

Install-Module : A parameter cannot be found that matches parameter name
'AllowPrerelease'.
At line:1 char:58
+ ... et\Install-Module posh-git -Scope CurrentUser -AllowPrerelease -Force
+                                                   ~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Install-Module], Paramet
   erBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Install-Module

阅读 github 站点上的勘误表，我看到它说我需要使用“Install-Module PowerShellGet -S”更新我的 PowerShellGet 模块
应对 CurrentUser -Force -AllowClobber"但这会产生错误:

PackageManagement\Install-Package : The module 'PackageManagement' cannot be
installed or updated because the authenticode signature of the file
'PackageManagement.cat' is not valid.
At C:\Program
Files\WindowsPowerShell\Modules\PowerShellGet\1.0.0.1\PSModule.psm1:1809
char:21
+ ...          $null = PackageManagement\Install-Package @PSBoundParameters
+                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (Microsoft.Power....InstallP
   ackage:InstallPackage) [Install-Package], Exception

我已经用谷歌搜索并尝试了几种方法来从我的笔记本电脑上显示的 v1.0.0.1 更新 PowerShellGet，但都无济于事。任何有关如何纠正此问题的建议将不胜感激。

Answer 1

错误是具体的。您正在为模块使用默认情况下不存在的参数/开关。

根据文档:

Prerelease Versioning Added to PowerShellGet and PowerShell Gallery

开发人员必须添加此内容，否则无法使用。

Publishers simply add the prerelease string (ie. the part that comes after “2.0.0”) in the metadata, and the version will be considered prerelease. For example:

@{
   ModuleVersion = '2.0.0'
   #---
      PrivateData = @{
         PSData = @{
            Prerelease = '-alpha'
      }
   }
}

这...

PowerShellGet\Install-Module

…也不是关于如何安装模块的常用方法(我知道)。您应该只需要 Install-Module cmdlet，PowerShell 已经知道它来自的模块并自动加载该模块(如果尚未加载)。

试试这个...

Find-Module -Name posh-git

Version    Name       Repository           Description
-------    ----       ----------           -----------
0.7.3      posh-git   PSGallery            Provides prompt ...



Find-Module -Name posh-git | 
Save-Module -Path "$env:USERPROFILE\Documents\WindowsPowerShell\Modules" # -WhatIf

What if: Performing the operation "Save Package" on target "'posh-git' to location 'C:\Users\Daniel\Documents\WindowsPowerShell\Modules'".


Install-Module -Name posh-git -Scope CurrentUser -Force
