损坏的包管理器？无法找到模块提供程序 (PowerShellGet)

Question

这是一个常见错误，我在网上找到的常见解决方案都没有解决。

无法运行 Get-PsRepository、Install-Module 和相关 (OneGet?) 命令，除非它们抛出“无法找到模块提供程序 (PowerShellGet)”错误。这似乎是 NuGet packagemanager 模块的问题，但我不知道如何恢复。安装的包提供程序似乎有效

症状模式：
C:> [Net.ServicePointManager]::安全协议

Tls12

获取 PSRepository

事实：
Windows 10 (1903)
Powershell 5.1.18362.1171
运行 PowerShell 作为管理员不在代理后面
可以访问 https://www.powershellgallery.com/api/v2
可以访问 nuget.org
`[Net.ServicePointManager]::SecurityProtocol = Tls12
FIPS 已禁用 (HKLM\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\Enabled DWORD=0)
Get-PackageProvider 仅显示 NuGet 2.8.5.208
PowerShellGet 版本为 1.0.0.1 ；当尝试使用 Install-Module PowerShellGet -Force 强制安装 sxs 时，我得到相同的结果：PackageManagement\Install-Package：无法找到模块提供程序 (PowerShellGet)。

Answer 1

我们遇到了同样的问题。发现这个线程没有解决方案。但我进一步挖掘了一下，在出现这个问题的计算机上，我们发现安装了 PackageManagement 1.4.7 版。删除后一切开始正常工作。我还没有找到这个东西是如何安装的。似乎是来自 Microsoft 的合法 powershell 模块，但它与 'normal' PowershellGet 模块交互并且似乎破坏了它。对于我们来说，它位于 %USERPROFILE%/document/WindowsPowershell/Modules。此 %USERPROFILE% 是公司 OneDrive 也毫无价值。

Answer 2

没有足够的代表发表评论。

I ended up in the same situation. A Windows 10 1909 machine, with %USERPROFILE%/document being a corporate OneDrive. Moving PackageManagement out of /WindowsPowerShell/ changed Get-PSRepository's output from nothing to PSGallery. Thanks! – tmcg Mar 1 at 21:35 This was exactly the same issue. I suspect this is because PowerShell 7 dumped it into this location (possibly Visual Studio Code when it prompt to update?) – aolszowka Mar 1 at 22:09

我在个人资料的 %USERPROFILE%/documents 中遇到了与包管理相同的问题。当我在这台新机器上安装 VScode 和 Powershell 扩展时，文件日期匹配。

从模块中删除文件夹暂时解决了问题。
