我的 Powershell v5.1 不会使用以下命令自动安装几乎任何模块install-module而手动安装确实有效。
首先，当我跑步时install-module，它会下载模块然后抛出错误，比如 pscx 模块：
PackageManagement\Install-Package : Package 'Pscx' failed to be installed because: Specified cast is not valid.
At C:\Program Files\WindowsPowerShell\Modules\PowerShellGet\2.0.4\PSModule.psm1:9307 char:21
+ ... $null = PackageManagement\Install-Package @PSBoundParameters
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidResult: (Pscx:String) [Install-Package], Exception
+ FullyQualifiedErrorId : Package '{0}' failed to be installed because: {1},Microsoft.PowerShell.PackageManag
ement.Cmdlets.InstallPackage
我现在能做的就是手动下载模块并使用import-module我。几乎每次我尝试通过此 cmdlet 安装任何模块时都会发生该错误。我该如何解决这个问题？
为了排除故障，Get-PSRepository给了我这个：
PS C:\> Get-PSRepository
Name InstallationPolicy SourceLocation
---- ------------------ --------------
PSGallery Trusted https://www.powershellgallery.com/api/v2
GalleryRolling Trusted https://www.poshtestgallery.com/api/v2/
EDIT:
尝试使用时遇到同样的错误Save-Module:
PS C:\> Find-Module -Name 'pscx' | Save-Module -Path "G:\Temp\System Documents\WindowsPowerShell\Modules"
WARNING: Package 'Pscx' failed to be installed because: Specified cast is not valid.
WARNING: Package 'Pscx' failed to install.
PackageManagement\Save-Package : Unable to save the module 'Pscx'.
At C:\Program Files\WindowsPowerShell\Modules\PowerShellGet\2.0.4\PSModule.psm1:11331 char:25

+ CategoryInfo : InvalidOperation: (Microsoft.Power...ets.SavePackage:SavePackage) [Save-Packag
e], Exception

它下载了包然后显示WARNING.
当使用Find-Module单独使用，结果是：
PS C:\> Find-Module -Name 'pscx'

EDIT 2:
哦，我忘了说，下载进程栏消失后，特定下载文件夹中没有创建任何文件。这是否意味着下载失败？

-Scope CurrentUser抛出同样的错误。

然后我尝试列出可用的模块：
