This appears everytime whenever I open my powershell. What can I do to fix this?

Looking for a solution.

Answer 1

You need to update the PSReadLine module. Run:

Install-Module PsReadLine -Force

Answer 2

I had the same exact issue. It occurred for me when trying to change my theme in the oh-my-posh init line in $profile. Running Install-Module PsReadLine -Force fixed the error, but my theme still didn't change. When editing $PROFILE make sure you put in

oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH/ENTER-THEME-NAME-HERE.omp.json" | Invoke-Expression

and not

oh-my-posh init pwsh --config "~/ENTER-THEME-NAME-HERE.omp.json" | Invoke-Expression

The page is wrong under the powershell tab under the Config syntax paragraph.

Hope this helps.
