A parameter cannot be found that matches parameter name 'TokenKind'

Question

I have beautified my Powershell according to this blog, but the Operator and Parameter are grey as follows:

So I change their colors by Set-PSReadlineOption:

Set-PSReadlineOption -TokenKind Operator -ForegroundColor Yellow

but get the following errors:

Set-PSReadLineOption : A parameter cannot be found that matches parameter name 'TokenKind'。

所在位置行:1 字符: 22

Set-PSReadlineOption -TokenKind Operator -ForegroundColor Yellow

CategoryInfo : InvalidArgument: (:) [Set-PSReadLineOption]，ParameterBindingException

FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.SetPSReadLineOption

But the help documents of Set-PSReadlineOption shows that it has a TokenKind parameter which in turn can have Operator as its parameter.

I'm confused why this error happens.

My powershell version is

Thanks for any suggestions!

They made a breaking change PSReadline V2, read about it here: https://github.com/lzybkr/PSReadLine/issues/738

So instead of

Set-PSReadlineOption -TokenKind String -ForegroundColor Magenta
Set-PSReadlineOption -TokenKind Variable -ForegroundColor Cyan

You would do something like

$colors = @{}
$colors['String'] = [System.ConsoleColor]::Magenta
$colors['Variable'] = [System.ConsoleColor]::Cyan
Set-PSReadLineOption -Colors $colors

I think there is a way to specify foreground/background color in the hashtable as well, but haven't figured out yet.

Read the Set-PSReadLineOption doc here.

Thanks for your information! After reading the Issue 738, I find that `Set-PSReadLineOption -Colors @{Operator = "Yellow"; Parameter = "Yellow"; Command = "Blue";String = "DarkYellow"}` just works as I expected. Thanks again! – Z-Y.L Oct 09 '18 at 12:18
