Question

我刚开始从Microsoft虚拟学院学习PowerShell，并且正在运行所示的命令之一。在他们的工作上，我的工作却没有。我确实到处寻找解决此问题的方法。我只是不知道出了什么问题。任何提示将对该新的PowerShell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SuperUser帖子，但是因为它在这里。

这种错误很常见，在大多数情况下是预期的。

并非所有帮助文件都会由于各种原因而按预期进行更新，大多数情况下，它会对关联的更新链接进行更新。如错误消息中所示。

许多模块没有在线可更新的帮助，或者URL已被删除。

可以安全地忽略这些错误。它们不会影响PS的功能或使用。

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

或者，如果您想查看与此相关的所有消息，那么...

Update-Help -Force -Verbose -ErrorAction SilentlyContinue
