Powershell “'get-error' 未被识别为 cmdlet 的名称

Question

Get-Error should be one of the basic PS commands, but it doesn't work for me. I get an error:

get-error : The term 'get-error' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

I updated the module Microsoft.PowerShell.Utility. I've checked the list of commands in it with:

Get-Command -Module Microsoft.PowerShell.Utility

And it is still not there.

Does anyone know how to fix it or how to get detailed error info without it?

Thanks!

Powershell errors are objects, just like everything else. As such, you can interrogate their properties and invoke their methods. They're documented on MSDocs as System.Management.Automation.ErrorRecord .

When I forced an error, and looked at the object with Get-Member , I saw

PS D:\Scripts> $error[0] | Get-Member


   TypeName: System.Management.Automation.ErrorRecord

Name                  MemberType     Definition

PS D:\Scripts>

but using the MSDocs will give you more useful information.

I installed Powershell core from https://github.com/powershell/powershell It seems to be available in Powershell core.
