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

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

enter image description here enter image description here

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'。

  • 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!

Solution

  • 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.
