Powershell 不会使用 install-module 安装几乎任何模块 [英] Powershell won't install almost any module using install-module
问题描述
我的 Powershell v5.1 几乎不会使用 install-module 自动安装任何模块，而手动安装确实可以.
My Powershell v5.1 won't install almost any module automatically using install-module whereas manually installation does work.
首先，当我运行 install-module 时，它会下载模块然后抛出一个错误，比如 pscx 模块:
First, when I run install-module, it would download the module then throw an error, say the pscx module:
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
我现在可以做的是手动下载模块并自己使用import-module.当我尝试通过此 cmdlet 安装任何模块时，几乎每次都会发生该错误.我该如何解决这个问题?
What I can do now is to manually download the module and use import-module myself. The error occurs almost every time when I'm trying to install any module through this cmdlet. How can I address this problem?
对于故障排除，Get-PSRepository 给了我这个:
For troubleshooting, Get-PSRepository gives me this:
PS C:\> Get-PSRepository
Name InstallationPolicy SourceLocation

尝试使用 Save-Module 时遇到同样的错误:
Got the same error when trying to use 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.

它下载了包然后显示WARNING.
单独使用Find-Module时，结果为:

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文件.这是否意味着下载失败?
Oh I forgot to say that there are no files created in the specific download folder after the download process bar disappeared. Does that mean the download has failed?

- 调试日志
- 我总是以管理员身份运行 PS.
-Scope CurrentUser抛出同样的错误.PS C:\>Uninstall-Module -Name "PowerShellGet"和PS C:\>Uninstall-Script -Name "PowerShellGet" -RequiredVersion 2.0.3产生相同的结果.
- Debugging log
- I Always run PS as administrator.
-Scope CurrentUserthrows the same error.Both
PS C:\> Uninstall-Module -Name "PowerShellGet"andPS C:\> Uninstall-Script -Name "PowerShellGet" -RequiredVersion 2.0.3produce the same result.

推荐答案
最终解决:
[Net.ServicePointManager]::SecurityProtocol = "tls12"
解决方案来自以下 博客范布伦克:
试图在代理后面安装 PowerShell 模块?您可能会收到此错误:无法解析包源https://www.powershellgallery.com/api/v2/".事实证明它不允许通过您的代理服务器 [...] 现在您运行的每个命令都通过代理发送和允许.
Trying to install a PowerShell module behind a proxy? Chances are you're getting this error: "Unable to resolve package source 'https://www.powershellgallery.com/api/v2/'". Turns out it isn't allowed through your proxy server [...] Now every command you run is sent and allowed through the proxy.
