powershell 更新帮助失败

Question

我刚刚开始从 Microsoft 虚拟学院学习 PowerShell，并且正在运行指定的命令之一。而在他们的一端，它起作用了，而我的却没有。我确实四处寻找解决这个问题的方法。我只是不知道出了什么问题。任何提示都会对 PowerShell 新学习者有所帮助。

PS C:\Windows\system32> Update-Help -Force
Update-Help : Failed to update Help for the module(s) 'WindowsUpdateProvider' with UI culture(s) {en-US} : Unable to retrieve the HelpInfo XML file for UI culture en-US. Make sure the
HelpInfoUri property in the module manifest is valid or check your network connection and then try the command again.

同意，这应该是一个 super 用户帖子，但既然它就在这里。

这种错误很常见，并且在大多数情况下都是预料之中的。

由于各种原因，并非所有帮助文件都会按预期更新，大多数时候都是与关联的更新链接有关。如您的错误消息所示。

许多模块要么没有在线可更新的帮助，要么 URL 已被删除。

可以安全地忽略这些类型的错误。它们不会影响 PS 功能或使用。

Get-Module -ListAvailable | Where HelpInfoUri | Update-Help

或者，如果您想查看所有与此相关的消息，请执行...

Update-Help -Force -Verbose -ErrorAction SilentlyContinue
