我刚开始从 Microsoft 虚拟学院学习 PowerShell,并且正在运行指示的命令之一。虽然在他们的最后它起作用了,但我却没有。我确实四处寻找解决此问题的方法。我只是不知道出了什么问题。任何提示都会对这个新的 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,这应该是一个超级用户帖子,但既然它在这里。

这种错误很常见,在大多数情况下都是预期的。

不是所有的帮助文件,由于各种原因按预期更新,大部分时间它与更新链接相关联。如您的错误消息所示。

许多模块要么没有在线可更新帮助,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,如果您想查看所有消息与此来回传递,请执行...

Update-Help -Force -Verbose -ErrorAction SilentlyContinue
